From 30a6ed0ce4bb18212ec38cdb537ea4b43bc99b83 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Tue, 28 Jan 2025 09:57:32 +0900 Subject: Track per-relation cumulative time spent in [auto]vacuum and [auto]analyze This commit adds four fields to the statistics of relations, aggregating the amount of time spent for each operation on a relation: - total_vacuum_time, for manual vacuum. - total_autovacuum_time, for vacuum done by the autovacuum daemon. - total_analyze_time, for manual analyze. - total_autoanalyze_time, for analyze done by the autovacuum daemon. This gives users the option to derive the average time spent for these operations with the help of the related "count" fields. Bump catalog version (for the catalog changes) and PGSTAT_FILE_FORMAT_ID (for the additions in PgStat_StatTabEntry).
