From 1ed1b84bdcd26abf3c4d08a9cf1aa9f7834262ab Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Wed, 26 Apr 2023 07:30:42 +0900 Subject: [PATCH] Re-add tracking of wait event SLRUFlushSync SLRUFlushSync has been accidently removed during dee663f, that has moved the flush of the SLRU files to the checkpointer, so add it back. The issue has been noticed by Thomas when checking for orphaned wait events.
