Thread: Unable to run psql on 9.5 after broken 12 remove
I have a production server running pg9.5 seamlessly.
Yesterday I decided to install libpq to have some crypto functions.
Unexpectedly, it installed postgresql 12 and its libpq.
I don't need pg 12, so I decided to remove it.
It did not went well
root@datastore-1:/home/user# apt-get --purge remove postgresql-client-12

The following package was automatically installed and is no longer required:
libuuid-perl
Use 'apt-get autoremove' to remove it.
The following packages will be REMOVED:
postgresql-12* postgresql-client-12* postgresql-contrib*
0 upgraded, 0 newly installed, 3 to remove and 89 not upgraded.
1 not fully installed or removed.
After this operation, 30.9 MB disk space will be freed.

After upgrading python the InvalidUrl is gone, but I still can't run psql Output of pg_lsclusters, if needed root@datastore-1:/usr/share/postgresql-common# pg_lsclusters Ver Cluster Port Status Owner Data directory Log file 9.5 main 6543 online postgres /var/lib/postgresql/9.5/main /var/log/postgresql/postgresql-9.5-main.log 12 main 5432 down,binaries_missing <unknown> /var/lib/postgresql/12/main /var/log/postgresql/postgresql-12-main.log I followed https://askubuntu.com/questions/1223270/psql-command-error-postgresql-version-12-is-not-installed with no luck, apt-purge simply states that pg12 is not installed.

Looks like the cluster was not removed from the pgcommon setup. This would explain why you can't run psql. By default pgcommon looks for the version of psql connected with the most recent version of Postgres it knows about, in this case 12. Unfortunately that binary no longer exists. You still have psql.

OK, it confirms that 9.5 client is still ok

This reported a warning
root@datastore-1:/home/user# pg_dropcluster 12 main
Warning: corrupted cluster: data directory does not exist
... but it did its job
root@datastore-1:/home/user# sudo -u postgres psql
psql (9.5.6)
Type "help" for help.
postgres=# \q
Thanks, you saved my day again!

Yeah, I'm guessing the original uninstall clean up process went off the
rails here:
