Thread: pgsql: Fix stats_fetch_consistency with stats for fixed-numbered object
Fix stats_fetch_consistency with stats for fixed-numbered objects This impacts the statistics retrieved in transactions for the following views when updating the value of stats_fetch_consistency, leading to behaviors contrary to what is documented since 605994651b6a as an update of this parameter should discard all statistics snapshot data: - pg_stat_archiver - pg_stat_bgwriter - pg_stat_checkpointer - pg_stat_io - pg_stat_slru - pg_stat_wal For example, updating stats_fetch_consistency from "snapshot" to "cache" in a transaction did not re-fetch any fresh data, using data cached from the time when "snapshot" was in use.
