The best explanation I can see for that is that the server is on
some other machine than where you are running psql/cat.

I guess it's at least theoretically possible that the server was
originally started in /var/lib/postgresql/data and somebody moved
that directory since then.

In any case, none of this looks like a Postgres bug; it looks
like sloppy sysadmin work. You're going to have to puzzle out
what's been done in that installation by yourself, because the
rest of us don't have the facts available.
