From 30e93d695428789b173c7ee32ecd14fbebc5b68c Mon Sep 17 00:00:00 2001 From: Shlok Kyal Date: Mon, 8 Sep 2025 21:04:42 +0530 Subject: [PATCH v5 1/2] Add stats related to slot sync skip When slot sync is performed, it can happen that it is skipped due to various reason. This patch adds stats for synced slots regarding this slot sync skip. This patch adds new columns slot_sync_skip_count, last_slot_sync_skip to view pg_stat_replication_slots and new column slot_sync_skip_reason to view pg_replication_slots. --- contrib/test_decoding/expected/stats.out | 12 ++-- doc/src/sgml/monitoring.sgml | 20 +++++++ doc/src/sgml/system-views.sgml | 8 +++ src/backend/catalog/system_views.sql | 5 +- src/backend/replication/logical/slotsync.c | 61 +++++++++++++++++++- src/backend/replication/slotfuncs.c | 26 ++++++++- src/backend/replication/walreceiver.c | 3 + src/backend/utils/activity/pgstat_replslot.c | 25 ++++++++ src/backend/utils/adt/pgstatfuncs.c | 18 ++++-- src/include/catalog/pg_proc.dat | 12 ++-- src/include/pgstat.h | 3 + src/include/replication/slot.h | 18 ++++++ src/test/regress/expected/rules.out | 9 ++- src/tools/pgindent/typedefs.list | 1 + 14 files changed, 199 insertions(+), 22 deletions(-) diff --git a/contrib/test_decoding/expected/stats.out b/contrib/test_decoding/expected/stats.out index 28da9123cc8..933dc0f08af 100644 --- a/contrib/test_decoding/expected/stats.out +++ b/contrib/test_decoding/expected/stats.out @@ -78,17 +78,17 @@ SELECT slot_name, spill_txns = 0 AS spill_txns, spill_count = 0 AS spill_count, -- verify accessing/resetting stats for non-existent slot does something reasonable SELECT * FROM pg_stat_get_replication_slot('do-not-exist');
