Hi Srinivas,
Thanks for reaching out to me.
We are not in the process of setting up the hot-standby.
we are in the process of testing the DR databases, so we want to place the
standby database out of sync from PROD by disabling the replication on DR
site , place the DR database in read-write mode for testing purpose, once
the application testing is done, we would like to place the DR database
back in sync with PROD.

NOTE: For Hot-standby we are using rsync method.

another question on postgres database logs: Is there any other location for
the log files apart from "/var/log/postgresql" location?

Regards,
Prashanth

Then after the maintenance, recv or fsync makes transaction commit wait for XLOG to be received or fsync-ed by the stand by database.
