From 0e42d31b0b2273c376ce9de946b59d155fac589c Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Wed, 26 Feb 2025 16:48:54 +0900 Subject: Adding new PgStat_WalCounters structure in pgstat.h This new structure contains the counters and the data related to the WAL activity statistics gathered from WalUsage, separated into its own structure so as it can be shared across more than one Stats structure in pg_stat.h. This refactoring will be used by an upcoming patch introducing backend-level WAL statistics. Bump PGSTAT_FILE_FORMAT_ID.
