A PostgreSQL Developer's Perspective: Five Interesting Patches From September's Commitfest

The PostgreSQL community recently completed a commitfest, a monthly event where the community reviews and discusses patches to improve the database. During this process, 65 patches were committed, 40 received feedback, 177 will be reviewed in the next commitfest, and 3 were rejected. The patches discussed here include improvements in memory management, logical replication, planner support for ORDER BY/DISTINCT, Kerberos delegation, and role memberships. These patches aim to address various issues and provide a better user experience, particularly for database users and application developers. The selected patches are notable because they offer significant performance wins, improve the overall user experience, and enhance PostgreSQL's capabilities in areas such as memory management and logical replication.
