Best guess is you are using a version of psql that is expecting the
socket to be somewhere else then where it actually is.
Is "permission denied" really the error you get when the socket does not exist?
Trying "psql --host=/var/run/foo" gave me "No such file or directory".
The OP used:
psql postgres
In that case psql will use the default set when it is compiled against libpq which from here:
https://www.postgresql.org/docs/16/libpq-connect.html#LIBPQ-PARAMKEYWORDS
"... is to connect to a Unix-domain socket in /tmp (or whatever socket directory was specified when PostgreSQL was built)"
If you have more then one instance of psql on a machine and they where built with different defaults you can
end up not hitting the right socket.
Also "permission denied" could be due to any part of the path /tmp/.s.PGSQL.5432.
