Subject: Replication Testing- How to introduce a Lag
Date: Fri, 20 Mar 2026 06:33:32 +0000
Message-ID: <[email protected]> (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
