| 17.2 | Nov 21, 2024 | New Release | The issues listed below affect PostgreSQL 17. Some of these issues may also affect other supported versions of PostgreSQL: Restore functionality of ALTER ROLE .. SET ROLE and ALTER DATABASE .. SET ROLE. The fix for CVE-2024-10978 accidentally caused settings for role to not be applied if they came from non-interactive sources, including previous ALTER {ROLE|DATABASE} commands and the PGOPTIONS environment variable. Restore compatibility for the timescaledb and other PostgreSQL extensions built using PostgreSQL prior to the 2024-11-14 release (17.0, 16.4, 15.8, 14.13, 13.16, 12.20, and earlier). This fix restores struct ResultRelInfo to its previous size, so that affected extensions don't need to be rebuilt. Fix cases where a logical replication slot's restart_lsn could go backwards. Avoid deleting still-needed WAL files during pg_rewind. Fix race conditions associated with dropping shared statistics entries, which could lead to loss of statistics data. Fix crash with ALTER TABLE when checking to see if an index's opclass options have changed if the table has an index with a non-default operator class. |
| 17.1 | Nov 14, 2024 | New Release | Ensure cached plans are marked as dependent on the calling role when RLS applies to a non-top-level table reference (Nathan Bossart) § If a CTE, subquery, sublink, security invoker view, or coercion projection in a query references a table with row-level security policies, we neglected to mark the resulting plan as potentially dependent on which role is executing it. This could lead to later query executions in the same session using the wrong plan, and then returning or hiding rows that should have been hidden or returned instead. The PostgreSQL Project thanks Wolfgang Walther for reporting this problem. (CVE-2024-10976) Make libpq discard error messages received during SSL or GSS protocol negotiation (Jacob Champion) § An error message received before encryption negotiation is completed might have been injected by a man-in-the-middle, rather than being real server output. Reporting it opens the door to various security hazards; for example, the message might spoof a query result that a careless user could mistake for correct output. The best answer seems to be to discard such data and rely only on libpq's own report of the connection failure. The PostgreSQL Project thanks Jacob Champion for reporting this problem. (CVE-2024-10977) Fix unintended interactions between SET SESSION AUTHORIZATION and SET ROLE (Tom Lane) § § The SQL standard mandates that SET SESSION AUTHORIZATION have a side-effect of doing SET ROLE NONE. Our implementation of that was flawed, creating more interaction between the two settings than intended. Notably, rolling back a transaction that had done SET SESSION AUTHORIZATION would revert ROLE to NONE even if that had not been the previous state, so that the effective user ID might now be different from what it had been before the transaction. Transiently setting session_authorization in a function SET clause had a similar effect. A related bug was that if a parallel worker inspected current_setting('role'), it saw none even when it should s |
| 17.0 | Sep 26, 2024 | New Release | New memory management system for VACUUM, which reduces memory consumption and can improve overall vacuuming performance. New SQL/JSON capabilities, including constructors, identity functions, and the JSON_TABLE() function, which converts JSON data into a table representation. Various query performance improvements, including for sequential reads using streaming I/O, write throughput under high concurrency, and searches over multiple values in a btree index. New client-side connection option, sslnegotiation=direct, that performs a direct TLS handshake to avoid a round-trip negotiation. pg_basebackup now supports incremental backup. COPY adds a new option, ON_ERROR ignore, that allows a copy operation to continue in the event of an error. Logical replication enhancements, including: Failover control pg_createsubscriber, a utility that creates logical replicas from physical standbys pg_upgrade now preserves replication slots on both publishers and subscribers |
