Thanks JD for the response. My question is more specific on how to reinstall old binary using apt-get install.

Thanks,
Suya

Hi,

You can follow below steps:

1. Stop the cluster .
2. If you have backup of old bin and postgresql.conf revert it and start .
3. Or uninstall and reinstall old binaries again.

Hi,

Good day all.

I’ve upgraded PG from 9.3.4 to 9.3.13 using apt-get install postgresql-9.3. I’m wondering as a blackout plan, how to downgrade it back to 9.3.4?

Thanks,
Suya
