Subject: Replication Testing- How to introduce a Lag
Date: Fri, 20 Mar 2026 06:33:32 +0000
Message-ID: <aadb9058660d4e10b5cee44b82458802@alte-leipziger.de> (raw)
Hello,
I have set up streaming replication in a our test environment and it is working OK .
1. Is there a way to force a lag between the source and the stand-by in an environment where there is NO load?
1. During the set up process as I was thrashing around from server to server I received this message in the stand-by if I make the standby follow a new server B after it had been following a server A. what seems to work is, additionally clearing out the archive logs dir of the standby server along with the data dir, before running the pg_basebackup from the standby. I am extremely new to postgres and I want to make sure that what I am doing is not a dangerous practice.
FATAL: requested timeline 2 is not a child of this server's history
LG
Ram
