Michael Paquier 2421e9a51d Remove read/sync fields from pg_stat_wal and GUC track_wal_io_timing ... The four following attributes are removed from pg_stat_wal: * wal_write * wal_sync * wal_write_time * wal_sync_time a051e71e28 has added an equivalent of this information in pg_stat_io with more granularity as this now spreads across the backend types, IO context and IO objects. So, keeping the same information in pg_stat_wal has little benefits. Another benefit of this commit is the removal of PendingWalStats, simplifying an upcoming patch to add per-backend WAL statistics, which already support IO statistics and which have access to the write/sync stats data of WAL. The GUC track_wal_io_timing, that was used to enable or disable the aggregation of the write and sync timings for WAL, is also removed. pgstat_prepare_io_time() is simplified. Bump catalog version. Bump PGSTAT_FILE_FORMAT_ID, due to the update of PgStat_WalStats.
