IIRC, part of the startup process involves chdir'ing to where the initdb
executable is and then chdir'ing back to whatever directory had been
current when you called initdb.  I speculate the other guy was root and
did "su postgres" not "su - postgres", so his cwd was still root's home
directory.

This might be harmless as long as you gave an absolute path for PGDATA
to initdb, but I'd still recommend using su - not just su.
