Thank you.
Seems that I all my problems are related to tmp folders being cleared after
every reboot. SOme of them, like postgres locks are recreated with old
permissions.

Will have to write a script to solve this. To my surprise, pgpool install
does not take care of this. At least not in 10.04.

Thanks again.
