Version 2.3.1 (2025-11-27)¶
Release highlights¶
This release adds compatibility with PostgreSQL 18 and introduces three new monitoring metrics for improved visibility into write-ahead log (WAL) and parallel workers.
Important
The previous PGSM 2.3.0 version is considered to be unreleased, please use the current 2.3.1 version instead.
Improvements¶
- Fixed a memory consumption issue that could lead to an assertion failure and cause server crashes in some workloads.
Added the following new metrics:
- wal_buffers_full, counts the number of times the WAL buffers became full
- parallel_workers_to_launch, tracks the number of planned parallel workers
- parallel_workers_launched, tracks the number of parallel workers actually launched
These metrics align with equivalent values in pg_stat_statements.
Bug fix¶
PG-2005 - Fixed a crash in pg_stat_monitor caused by exceeding internal stack depth during parsing of deeply nested statements.
