su postgres in logs

[jkls]

I have the postgres server installed and not configured.
One of many such messed up servers.

I'm reading the auth logs and there is a
su[239]: + console root-postgres line.
Is this a normal system login from a cron job or something?
It wasn't me doing this su command.
I guess this info might be in the
Postgres Administrator's guide but
I can't get around to that for some time to come.

There are several lines of  "session opened for user postgres" as well.
Why is this? Can it just be the server starting up?

I've disabled the postgres startup now anyway.
