Fix permissions on PG_VERSION

[krsyoung]

Thanks! That was almost perfect. One issue is that the check for PG_VERSION fails because the "non-root" root is trying to access a postgres owned file. I just chmodded the pgdata folder to 744 before the check and back to 700 after. Worked like a charm!

I need to figure out what is going on here as I don't seem to have this issue ... if anybody else has experienced it I'd love to hear about it.
