  • Several fixes for partitioning, including potential crashes as well as allowing TRUE and FALSE as part bounds

  • Fix ” CREATE TABLE … LIKE “with bigint identity columns on 32-bit platforms
  • Fix memory leak within the runtime of a query that has executes hash joins
  • Several crash fixes around queries using GROUPING SET
  • a query-cancel or session-termination interrupt occurs while committing a prepared transaction
  • Reduce locking during autovacuum worker scheduling, which prevents loss of potential worker concurrency
  • Fix possible slow execution of REFRESH MATERIALIZED VIEW CONCURRENTLY
  • Several fixes around query plans that use “index-only” scans
  • Avoid deadlocks in competitor CREATE INDEX CONCURRENTLY commands that are run under SERIALIZABLE or REPEATABLE READ transaction isolation
  • Several fixes for SP-GiST indexes , including one collation-aware searches on text columns
  • Fixes related to counting the number of tuples in partial GiST, SP-GiST, and Bloom indexes
  • Several fixes for logical decoding and replication
  • Fix misquoting of values ​​for list-valued GUC variables (eg local_preload_libraries, session_preload_libraries, shared_preload_libraries, temp_tablespaces) in dumps
  • Several fixes for pg_stat_activity
  • Several fixes for ecpg
  • Fix for pg_recvlogical to ensure compatibility with PostgreSQL versions released before 10
