Time to upgrade postgres. If I pull this off without fucking something up, I'm going to reward myself with cute catgirl anime

I've recently done this (on Debian Sid):
# pg_dropcluster --stop 13 main
# pg_upgradecluster 12 main
# pg_dropcluster 12 main
I only have a single database for akonadi/KMail though, so that may simplify things a bit/lot.
pg_upgradecluster does a lot of useful things. It upgrades the main cluster from version 12 to 13, changes the ports so that 13 runs on the default port and 12 on a different one and gives nice instructions on what it has done and what you should do next.
