It's a single binary with multiple names, which behaves differently
depending on which name is used to invoke it. If you start it as
'postmaster', it runs as a daemon and handles incoming connections.
If you invoke it as 'postgres', it starts a "standalone backend",
which is only used for fixing certain rare problems.
So no, invoking it as 'postgres' will keep it from working correctly.
