PostgreSQL JDBC Driver 42.1.2 Released

Changed

  • Better logic for returning keyword detection. Previously, pgjdbc could be defeated by column names that contain returning, so pgjdbc failed to “return generated keys” as it considered statement as already having returning keyword PR 824 201daf1d
  • Use server-prepared statements for batch inserts when prepareThreshold>0. Note: this enables batch to use server-prepared from the first executeBatch() execution (previously it waited for prepareThreshold executeBatch() calls) abc3d9d7

Fixed

  • Replication API: fix issue in #834 setting statusIntervalUpdate causes high CPU load. PR 835 59236b74

Regressions

  • NPE in PreparedStatement.executeBatch in case of empty batch. Fixed in 42.1.3
