Hmm - so you can't "su - postgres" because as "admin" you'll need a password.
Off the top of my head you could:

1. chmod PG's startup script, so it runs suid as postgres (chmod u+s)
2. Use ssh to login as user postgres on localhost and execute pg_ctl start
(you can setup ssh so it doesn't need a password)

Either of those should work, with a little effort.
