Re: Swapping master and slave

Hi Yambu,

If you have a failover tool like EDB EFM,repmgr or others then it will
automatically take care of promoting the standby to master and
reconfiguring old master as new slave when you do a switchover.

If you don't have such tools then you can manually promote the standy to be
the new master and run a pg_rewind on the old master to sync with the new
master. If pg_rewind does not work then you will have to rebuild the old
master using pg_basebackup.

Thanks and Regards,
Nikhil
