Re: Turn off streaming replication - leaving Master running - Mailing list pgsql-general
Cheers Micheal,
So i don't want to touch the file as this will promote it too a master - i would just like it as a standalone db for this instance - i need to load a db and do some testing.
After which i will delete the data directory and run the basebackup cmd and pull the db back from the master and set up streaming again.
Just need to be certain of the right steps so i don't effect the Master in any way.

What kind of tests? If this is read-only activity you could simply cut
the network connection between the master and the slave, or restart
the slave after updating recovery.conf such as it is still a standby
but has no primary_conninfo so as it is performing archive recovery,
or at least a fake one.

Well, yes. It depends on what you want to do then. If this testing
really requires to promote the standby then you will need to take a
new fresh base backup knowing that you are using 9.2.
