* [PATCH v3] Track skipped vacuum and analyze activity per relation @ 2026-03-24 04:09 Yugo Nagata <[email protected]> 0 siblings, 0 replies; 2+ messages in thread From: Yugo Nagata @ 2026-03-24 04:09 UTC (permalink / raw) This commit adds eight fields to the relation statistics that track the last time vacuum or analyze has been attempted but skipped due to lock unavailability, along with their counts: - last_skipped_vacuum - last_skipped_autovacuum - last_skipped_analyze - last_skipped_autoanalyze - skipped_vacuum_count - skipped_autovacuum_count - skipped_analyze_count - skipped_autoanalyze_count These field can help users confirm that autovacuum is actively attempting to run on a table that has not been vacuumed or analyzed for a long time, and that the lack of progress is due to repeated skips rather than inactivity. --- doc/src/sgml/monitoring.sgml | 80 +++++++++++++++++ src/backend/catalog/system_views.sql | 8 ++ src/backend/commands/vacuum.c | 95
