Thanks again:) I already ran into some of these. I actually started walking through errors and fixing them. The int4/bit casting, etc. Guess it makes more sense to use the version of postgres that is known to work with OACS... I have this horrible need to use the latest version of everything I install... so I can wait longer to upgrade in my mind;( There is flaw in that logic I know.
Thanks for reminding me the goal was to try out OACS! I am downgrading to postgres 7.2.x today:)
