What's new in this version:

- Avoid returning duplicate rows from hash right semi-joins
- Avoid possible out-of-memory failures during parallel GIN index build
- Several fixes for BRIN indexes
- Avoid duplicating hash partition constraints during DETACH CONCURRENTLY, which previously caused issues during dump/restore or if a parent table is dropped after the DETACH
- Disallow generated columns in partition keys and in COPY ... FROM ... WHERE clauses
- Avoid failures when synchronized_standby_slots references nonexistent replication slots
- Avoid unwanted WAL receiver shutdown when switching from streaming to archive WAL source
- Avoid unnecessary invalidation of logical replication slots
- Correctly handle GROUP BY DISTINCT in PL/pgSQL assignment statements
- Avoid leaking memory when handling a SQL error within PL/Python
- Ensure consistent ordering of foreign key constraints in the output of pg_dump
- Several fixes for pgbench error handling and reporting

Fixed:
- Fixes for crashes related to partitioned tables, including one occurring during a recheck
