DROP DATABASE
DROP DATABASE
DROP DATABASE - remove a database
Synopsis
DROP DATABASE [ IF EXISTS ]name[ [ WITH ] (option[, ...] ) ] whereoptioncan be: FORCE
Description
DROP DATABASE
drops a database. It removes the
catalog entries for the database and deletes the directory
containing the data. It can only be executed by the database owner.
It cannot be executed while you are connected to the target database.
(Connect to
postgres
or any other database to issue this
command.)
Also, if anyone else is connected to the target database, this command will
fail unless you use the
FORCE
option described below.
DROP DATABASE
cannot be undone. Use it with care!
Parameters
-
IF EXISTS -
Do not throw an error if the database does not exist. A notice is issued in this case.
-
name -
The name of the database to remove.
-
FORCE -
Attempt to terminate all existing connections to the target database. It doesn't terminate if prepared transactions, active logical replication slots or subscriptions are present in the target database.
This will fail if the current user has no permissions to terminate other connections. Required permissions are the same as with
pg_terminate_backend, described in Section 9.27.2 . This will also fail if we are not able to terminate connections.
Notes
DROP DATABASE
cannot be executed inside a transaction
block.
This command cannot be executed while connected to the target database. Thus, it might be more convenient to use the program dropdb instead, which is a wrapper around this command.
Compatibility
There is no
DROP DATABASE
statement in the SQL standard.
