PostgreSQL (64-bit)

What's new in this version:

Fixes and Improvements:
- Fix a breakage in the replication protocol by ensuring that two "command completion" events are expected for START_REPLICATION
- Ensure fsync is called on the SLRU caches that PostgreSQL maintains. This prevents potential data loss due to an operating system crash
- Fix ALTER ROLE usage for users with the BYPASSRLS permission
- ALTER TABLE ONLY ... DROP EXPRESSION is disallowed on partitioned tables when there are child tables
- Ensure that ALTER TABLE ONLY ... ENABLE/DISABLE TRIGGER does not apply to child tables
- Fix for ALTER TABLE ... SET NOT NULL on partitioned tables to avoid a potential deadlock in parallel pg_restore
- Fix handling of expressions in CREATE TABLE LIKE with inheritance
- DROP INDEX CONCURRENTLY is disallowed on partitioned tables
- Allow LOCK TABLE to succeed on a self-referential view instead of throwing an error
- Several fixes around statistics collection and progress reporting for REINDEX CONCURRENTLY
- Ensure that GENERATED columns are updated when any columns they depend on are updated via a rule or an updatable view
- Support hash partitioning with text array columns as partition keys
- Allow the jsonpath .datetime() method to accept ISO 8601-format timestamps
- During a "smart" shutdown, ensure background processes are not terminated until all foreground client sessions are completed, fixing an issue that broke the processing of parallel queries
- Several fixes for the query planner and optimizer
- Ensure that data is de-toasted before being inserted into a BRIN index. This could manifest itself with errors like "missing chunk number 0 for toast value NNN". If you have seen a similar error in an existing BRIN index, you should be able to correct it by using REINDEX on the index
- Fix the output of EXPLAIN to have the correct XML tag nesting for incremental sort plans
- Several fixes for memory leaks, including ones involving RLS policies, using CALL with PL/pgSQL, SIGHUP processing a configuration parameter that cannot be applied without a restart, and an edge-case for index lookup for a partition
- libpq can now support arbitrary-length lines in the .pgpass file
- On Windows, psql now reads the output of a backtick command in text mode, not binary mode, so it can now properly handle newlines
- Fix how pg_dump, pg_restore, clusterdb, reindexdb, and vacuumdb use complex connection-string parameters
- When the connect command of psql reuses connection parameters, ensure that all non-overridden parameters from a previous connection string are also re-used
- Ensure that pg_dump collects per-column information about extension configuration tables, avoiding crashes when specifying --inserts
- Ensure that parallel pg_restore processes foreign keys referencing partitioned tables in the correct order
- Several fixes for contrib/pgcrypto, including a memory leak fix
