I was running postgresql as a service on my NixOS machine.
$ grep postgres /etc/nixos/configuration.nix
services.postgresql.enable = true;
The data lived in /var/lib/postgresql/9.6
.
$ systemctl cat postgresql.service | grep PGDATA
Environment="PGDATA=/var/lib/postgresql/9.6"
I no longer need to run postgresql, so I’ve disabled (removed) the service in my nixos config.
I don’t care about the data, so I’d like to delete the /var/lib/postgresql/9.6
directory as well.
Is this the correct way to remove the remnants of postgresql from my system?
In other words, is it safe to delete and are there other locations I should check for “leftover” postgresql files/directories?
