From a493e741d32b7580abe4d0dcc444fcedd8feec6e Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Thu, 17 Jul 2025 09:30:26 +0900 Subject: [PATCH] Fix inconsistent LWLock tranche names for MultiXact* MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The terms used in wait_event_names.txt and lwlock.c were inconsistent for MultiXactOffsetSLRU and MultiXactMemberSLRU, which could cause joins between pg_wait_events and pg_stat_activity to fail. lwlock.c is adjusted in this commit to what the historical name of the event has always been, and what is documented. Oversight in 53c2a97a9266. 08b9b9e043bb has fixed a similar inconsistency some time ago.
