From 317632f3073fc06047a42075eb5e28a9577a4f96 Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Sat, 31 Jul 2021 09:50:26 +0300 Subject: Move InRecovery and standbyState global vars to xlogutils.c. They are used in code that runs both during normal operation and during WAL replay, and needs to behave differently during replay. Move them to xlogutils.c, because that's where we have other helper functions used by redo routines.
