Обсуждение: Installing multiple Postgresql Versions in parallel, does not seem to work anymore

Hello Listmembers, 

during a routine postgresql upgrade from 14 to 17 on a Debian 12 Server I stumbled over this behaviour:

The Server is Running Debian 12 and the postgresql.org apt repository. Until today the Server was running Postgresql 14 and an upgrade to postgresql 17 was planned. In the past I used to install the new version in parallel and migrated the data. Today I noticecd the post install steps did not run. No cluster was bootstrapped, no config directory created, no systemd unit created. There was also an upgrade planned to Debian 13, so I did this first, and tried again. Same result. 

I confirmed on a fresh Debian 13 server and the result is the same.
Please find the console log of the fresh Debian 13 Server attached.

Kind Regards,
Simon

The packages are co-installable. What changed is that no new cluster
is created by default. If you want that, run `pg_createcluster 17 main`.

But the packaging is built about pg_upgradecluster, so you might just
run `pg_upgradecluster 14 main -v 17` instead.
