Hi Adrian,

Thanks for answering on both sides!



Same response as to your SO question:

What is the output of pg_lsclusters?
Ver Cluster Port Status                Owner    Data directory              Log file 12  main    5432 down,binaries_missing postgres /var/lib/postgresql/12/main /var/log/postgresql/postgresql-12-main.log 13  main    5433 online                postgres /var/lib/postgresql/13/main /var/log/postgresql/postgresql-13-main.log



Your Postgres 13 cluster is up and listening on 5433.

Your choices:

1) Connect using psql -d <some_db> -U <some_user> -p 5433


2) Open:

sudo vi /etc/postgresql/13/main/postgresql.conf

and change

port = 5433

to

port = 5432

and then restart server.


While you are at it:

sudo pg_dropcluster 12 main

to get rid of the orphaned cluster.
