E.3.1. Overview #

PostgreSQL 17 contains many new features and enhancements, including:

  • New memory management system for VACUUM , which reduces memory consumption and can improve overall vacuuming performance.

  • New SQL/JSON capabilities, including constructors, identity functions, and the JSON_TABLE() function, which converts JSON data into a table representation.

  • Various query performance improvements, including for sequential reads using streaming I/O, write throughput under high concurrency, and searches over multiple values in a btree index.

  • Logical replication enhancements, including:

    • Failover control

    • pg_createsubscriber , a utility that creates logical replicas from physical standbys

    • pg_upgrade now preserves logical replication slots on publishers and full subscription state on subscribers. This will allow upgrades to future major versions to continue logical replication without requiring copy to resynchronize.

  • New client-side connection option, sslnegotiation=direct , that performs a direct TLS handshake to avoid a round-trip negotiation.

  • pg_basebackup now supports incremental backup.

  • COPY adds a new option, ON_ERROR ignore , that allows a copy operation to continue in the event of an error.

The above items and other new features of PostgreSQL 17 are explained in more detail in the sections below.

E.3.2. Migration to Version 17 #

A dump/restore using pg_dumpall or use of pg_upgrade or logical replication is required for those wishing to migrate data from any previous release. See Section 18.6 for general information on migrating to new major releases.

Version 17 contains a number of changes that may affect compatibility with previous releases. Observe the following incompatibilities:

  • Change functions to use a safe search_path during maintenance operations (Jeff Davis) § §

    This prevents maintenance operations ( ANALYZE , CLUSTER , CREATE INDEX , CREATE MATERIALIZED VIEW , REFRESH MATERIALIZED VIEW , REINDEX , or VACUUM ) from performing unsafe access. Functions used by expression indexes and materialized views that need to reference non-default schemas must specify a search path during function creation.

  • Restrict ago to only appear at the end in interval values (Joseph Koshakow) § §

    Also, prevent empty interval units from appearing multiple times.

  • Remove server variable old_snapshot_threshold (Thomas Munro) §

    This variable allowed vacuum to remove rows that potentially could be still visible to running transactions, causing "snapshot too old" errors later if accessed. This feature might be re-added to PostgreSQL later if an improved implementation is found.

  • Change SET SESSION AUTHORIZATION handling of the initial session user's superuser status (Joseph Koshakow) §

    The new behavior is based on the session user's superuser status at the time the SET SESSION AUTHORIZATION command is issued, rather than their superuser status at connection time.

  • Remove feature which simulated per-database users (Nathan Bossart) §

    The feature, db_user_namespace , was rarely used.

  • Remove adminpack contrib extension (Daniel Gustafsson) §

    This was used by now end-of-life pgAdmin III .

  • Remove wal_sync_method value fsync_writethrough on Windows (Thomas Munro) §

    This value was the same as fsync on Windows .

  • Change file boundary handling of two WAL file name functions (Kyotaro Horiguchi, Andres Freund, Bruce Momjian) §

    The functions pg_walfile_name() and pg_walfile_name_offset() used to report the previous LSN segment number when the LSN was on a file segment boundary; it now returns the current LSN segment.

  • Remove server variable trace_recovery_messages since it is no longer needed (Bharath Rupireddy) §

  • Remove information schema column element_types . domain_default (Peter Eisentraut) §

  • Change pgrowlocks lock mode output labels (Bruce Momjian) §

  • Remove buffers_backend and buffers_backend_fsync from pg_stat_bgwriter (Bharath Rupireddy) §

    These fields are considered redundant to similar columns in pg_stat_io .

  • Rename I/O block read/write timing statistics columns of pg_stat_statements (Nazir Bilal Yavuz) §

    This renames blk_read_time to shared_blk_read_time , and blk_write_time to shared_blk_write_time .

  • Change pg_attribute . attstattarget and pg_statistic_ext . stxstattarget to represent the default statistics target as NULL (Peter Eisentraut) § §

  • Rename pg_collation . colliculocale to colllocale and pg_database . daticulocale to datlocale (Jeff Davis) §

  • Rename pg_stat_progress_vacuum column max_dead_tuples to max_dead_tuple_bytes , rename num_dead_tuples to num_dead_item_ids , and add dead_tuple_bytes (Masahiko Sawada) § §

  • Rename SLRU columns in system view pg_stat_slru (Alvaro Herrera) §

    The column names accepted by pg_stat_reset_slru() are also changed.

E.3.3. Changes #

Below you will find a detailed account of the changes between PostgreSQL 17 and the previous major release.

E.3.3.1. Server #

E.3.3.1.1. Optimizer #

  • Allow the optimizer to improve CTE plans by considering the statistics and sort order of columns referenced in earlier row output clauses (Jian Guo, Richard Guo, Tom Lane) § §

  • Improve optimization of IS NOT NULL and IS NULL query restrictions (David Rowley, Richard Guo, Andy Fan) § §

    Remove IS NOT NULL restrictions from queries on NOT NULL columns and eliminate scans on NOT NULL columns if IS NULL is specified.

  • Allow partition pruning on boolean columns on IS [NOT] UNKNOWN conditionals (David Rowley) §

  • Improve optimization of range values when using containment operators <@ and @> (Kim Johan Andersson, Jian He) §

  • Allow correlated IN subqueries to be transformed into joins (Andy Fan, Tom Lane) §

  • Improve optimization of the LIMIT clause on partitioned tables, inheritance parents, and UNION ALL queries (Andy Fan, David Rowley) §

  • Allow query nodes to be run in parallel in more cases (Tom Lane) §

  • Allow GROUP BY columns to be internally ordered to match ORDER BY (Andrei Lepikhov, Teodor Sigaev) §

    This can be disabled using server variable enable_group_by_reordering .

  • Allow UNION (without ALL ) to use MergeAppend (David Rowley) §

  • Fix MergeAppend plans to more accurately compute the number of rows that need to be sorted (Alexander Kuzmenkov) §

  • Allow GiST and SP-GiST indexes to be part of incremental sorts (Miroslav Bendik) §

    This is particularly useful for ORDER BY clauses where the first column has a GiST and SP-GiST index, and other columns do not.

  • Add columns to pg_stats to report range-type histogram information (Egor Rogov, Soumyadeep Chakraborty) §

E.3.3.1.2. Indexes #

  • Allow btree indexes to more efficiently find a set of values, such as those supplied by IN clauses using constants (Peter Geoghegan, Matthias van de Meent) §

  • Allow BRIN indexes to be created using parallel workers (Tomas Vondra, Matthias van de Meent) §

E.3.3.1.3. General Performance #

  • Allow vacuum to more efficiently remove and freeze tuples (Melanie Plageman, Heikki Linnakangas) §

    WAL traffic caused by vacuum is also more compact.

  • Allow vacuum to more efficiently store tuple references (Masahiko Sawada, John Naylor) § § § §

    Additionally, vacuum is no longer silently limited to one gigabyte of memory when maintenance_work_mem or autovacuum_work_mem are higher.

  • Optimize vacuuming of relations with no indexes (Melanie Plageman) §

  • Increase default vacuum_buffer_usage_limit to 2MB (Thomas Munro) §

  • Improve performance when checking roles with many memberships (Nathan Bossart) §

  • Improve performance of heavily-contended WAL writes (Bharath Rupireddy) §

  • Improve performance when transferring large blocks of data to a client (Melih Mutlu) §

  • Allow the grouping of file system reads with the new system variable io_combine_limit (Thomas Munro, Andres Freund, Melanie Plageman, Nazir Bilal Yavuz) § § §

E.3.3.1.4. Monitoring #

  • Create system view pg_stat_checkpointer (Bharath Rupireddy, Anton A. Melnikov, Alexander Korotkov) § § §

    Relevant columns have been removed from pg_stat_bgwriter and added to this new system view.

  • Improve control over resetting statistics (Atsushi Torikoshi, Bharath Rupireddy) § § §

    Allow pg_stat_reset_shared() (with no arguments) and pg_stat_reset_shared( NULL ) to reset all shared statistics. Allow pg_stat_reset_shared('slru') and pg_stat_reset_slru() (with no arguments) to reset SLRU statistics, which was already possible with pg_stat_reset_slru(NULL).

  • Add log messages related to WAL recovery from backups (Andres Freund) §

  • Add log_connections log line for trust connections (Jacob Champion) §

  • Add log message to report walsender acquisition and release of replication slots (Bharath Rupireddy) §

    This is enabled by the server variable log_replication_commands .

  • Add system view pg_wait_events that reports wait event types (Bertrand Drouvot) §

    This is useful for adding descriptions to wait events reported in pg_stat_activity .

  • Add wait events for checkpoint delays (Thomas Munro) §

  • Allow vacuum to report the progress of index processing (Sami Imseih) §

    This appears in system view pg_stat_progress_vacuum columns indexes_total and indexes_processed .

E.3.3.1.5. Privileges #

  • Allow granting the right to perform maintenance operations (Nathan Bossart) §

    The permission can be granted on a per-table basis using the MAINTAIN privilege and on a per-role basis via the pg_maintain predefined role. Permitted operations are VACUUM , ANALYZE , REINDEX , REFRESH MATERIALIZED VIEW , CLUSTER , and LOCK TABLE .

  • Allow roles with pg_monitor membership to execute pg_current_logfile() (Pavlo Golub, Nathan Bossart) §

E.3.3.1.6. Server Configuration #
E.3.3.1.7. Streaming Replication and Recovery #

  • Add application pg_createsubscriber to create a logical replica from a physical standby server (Euler Taveira) §

  • Have pg_upgrade migrate valid logical slots and subscriptions (Hayato Kuroda, Hou Zhijie, Vignesh C, Julien Rouhaud, Shlok Kyal) § §

    This allows logical replication to continue quickly after the upgrade. This only works for old PostgreSQL clusters that are version 17 or later.

  • Enable the failover of logical slots (Hou Zhijie, Shveta Malik, Ajin Cherian) §

    This is controlled by an optional fifth argument to pg_create_logical_replication_slot() .

  • Add server variable sync_replication_slots to enable failover logical slot synchronization (Shveta Malik, Hou Zhijie, Peter Smith) § §

  • Add logical replication failover control to CREATE/ALTER SUBSCRIPTION (Shveta Malik, Hou Zhijie, Ajin Cherian) § §

  • Allow the application of logical replication changes to use hash indexes on the subscriber (Hayato Kuroda) §

    Previously only btree indexes could be used for this purpose.

  • Improve logical decoding performance in cases where there are many subtransactions (Masahiko Sawada) §

  • Restart apply workers if subscription owner's superuser privileges are revoked (Vignesh C) §

    This forces reauthentication.

  • Add flush option to pg_logical_emit_message() (Michael Paquier) §

    This makes the message durable.

  • Allow specification of physical standbys that must be synchronized before they are visible to subscribers (Hou Zhijie, Shveta Malik) § §

    The new server variable is synchronized_standby_slots .

  • Add worker type column to pg_stat_subscription (Peter Smith) §

E.3.3.2. Utility Commands #

  • Add new COPY option ON_ERROR ignore to discard error rows (Damir Belyalov, Atsushi Torikoshi, Alex Shulgin, Jian He, Yugo Nagata) § § § §

    The default behavior is ON_ERROR stop .

  • Add new COPY option LOG_VERBOSITY which reports COPY FROM ignored error rows (Bharath Rupireddy) §

  • Allow COPY FROM to report the number of skipped rows during processing (Atsushi Torikoshi) §

    This appears in system view column pg_stat_progress_copy . tuples_skipped .

  • In COPY FROM , allow easy specification that all columns should be forced null or not null (Zhang Mingli) §

  • Allow partitioned tables to have identity columns (Ashutosh Bapat) §

  • Allow exclusion constraints on partitioned tables (Paul A. Jungwirth) §

    As long as exclusion constraints compare partition key columns for equality, other columns can use exclusion constraint-specific comparisons.

  • Add clearer ALTER TABLE method to set a column to the default statistics target (Peter Eisentraut) §

    The new syntax is ALTER TABLE ... SET STATISTICS DEFAULT ; using SET STATISTICS -1 is still supported.

  • Allow ALTER TABLE to change a column's generation expression (Amul Sul) §

    The syntax is ALTER TABLE ... ALTER COLUMN ... SET EXPRESSION .

  • Allow specification of table access methods on partitioned tables (Justin Pryzby, Soumyadeep Chakraborty, Michael Paquier) § §

  • Add DEFAULT setting for ALTER TABLE .. SET ACCESS METHOD (Michael Paquier) §

  • Add support for event triggers that fire at connection time (Konstantin Knizhnik, Mikhail Gribkov) §

  • Add event trigger support for REINDEX (Garrett Thornburg, Jian He) §

  • Allow parenthesized syntax for CLUSTER options if a table name is not specified (Nathan Bossart) §

E.3.3.2.1. EXPLAIN #

  • Allow EXPLAIN to report optimizer memory usage (Ashutosh Bapat) §

    The option is called MEMORY .

  • Add EXPLAIN option SERIALIZE to report the cost of converting data for network transmission (Stepan Rutz, Matthias van de Meent) §

  • Allow the interval data type to support +/-infinity values (Joseph Koshakow, Jian He, Ashutosh Bapat) §

  • Allow the use of an ENUM added via ALTER TYPE if the type was created in the same transaction (Tom Lane) §

    This was previously disallowed.

E.3.3.4. MERGE #

  • Allow MERGE to modify updatable views (Dean Rasheed) §

  • Add WHEN NOT MATCHED BY SOURCE to MERGE (Dean Rasheed) §

    WHEN NOT MATCHED on target rows was already supported.

  • Allow MERGE to use the RETURNING clause (Dean Rasheed) §

    The new RETURNING function merge_action() reports on the DML that generated the row.

E.3.3.5. Functions #

  • Add function JSON_TABLE() to convert JSON data to a table representation (Nikita Glukhov, Teodor Sigaev, Oleg Bartunov, Alexander Korotkov, Andrew Dunstan, Amit Langote, Jian He) § §

  • Add to_timestamp() time zone format specifiers (Tom Lane) §

    TZ accepts time zone abbreviations or numeric offsets, while OF accepts only numeric offsets.

  • Allow the session time zone to be specified by AT LOCAL (Vik Fearing) §

    This is useful when converting adding and removing time zones from time stamps values, rather than specifying the literal session time zone.

  • Add functions uuid_extract_timestamp() and uuid_extract_version() to return UUID information (Andrey Borodin) §

  • Add functions to generate random numbers in a specified range (Dean Rasheed) §

  • Improve psql display of default and empty privileges (Erik Wienhold, Laurenz Albe) §

    Command \dp now displays (none) for empty privileges; default still displays as empty.

  • Have backslash commands honor \pset null (Erik Wienhold, Laurenz Albe) §

    Previously \pset null was ignored.

  • Allow psql 's \watch to stop after a minimum number of rows returned (Greg Sabino Mullane) §

    The parameter is min_rows .

  • Allow psql connection attempts to be canceled with control-C (Tristan Partin) §
