From c93001b3f957994942ea18ed261ae06ac507ea95 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Fri, 1 Feb 2019 10:46:45 +0900 Subject: [PATCH] Adjust comment about timeout when waiting for WAL at recovery A timeout of 5s is used when waiting for WAL to become available at recovery so as the startup process is able to react promptly if a trigger file shows up. However this missed the fact that the startup process also relies on the timeout to check periodically the status of any active WAL receiver.
