Re: Two started cluster on the same data directory and port

Indeed, that is the problem, they are two different clusters, pointing to the same data directory and reading from the same port.

I can't change the port because it is the same postgresql.conf

I don't know how to disassociate the main_old cluster from the data directory or how to resolve this situation.

Blaming it on not enough coffee, but I just noticed both clusters are
pointing at the same data directory. I would NOT do:

     sudo pg_dropcluster 14 main_old
