Query Performance Monitoring Tool for PostgreSQL
GH-646 - Resolving a possible issue that could lead to pg_stat_monitor deadlocking in pgsm_store.
Bugs Fixed GH-425 - pg_stat_monitor crashes PostgreSQL if Citus library is loaded
Release highlights This release adds support for PostgreSQL version 16 by resolving compilation and API change issues.
Release highlights This release fixes the server crash when running pgsm_enable_query_plan is enabled, addresses the incorrect behaviour with the non-default number of buckets configured, and improves the memory context handling for pg_stat_monitor.
Bugs Fixed PG-613 - Fixed the issue with segmentation fault error when the query plan is enabled on large queries. PG-624 - Fixed the server crash when running pgbench with pg_stat_monitor loaded by improving the handling of the dynamic number of buckets.
