Sounds to me like you're running pg_ctl with a $PGDATA setting that
doesn't match where the server actually lives.  Try
"show data_directory;" in psql to verify what the server thinks $PGDATA
is.

A less likely possibility is that some outside force removed the
$PGDATA/postmaster.pid file.  If that's the case, signal the postmaster
to shut down using "kill -TERM" (equivalent of normal shutdown) or "kill
-INT" (equivalent of fast shutdown) and then restart it to recreate the
pid file.  ("pg_ctl stop" is actually just a wrapper around these signal
operations...)
