[arch-dev-public] PostgreSQL 9.0.1 in [testing]

Community feedback welcome as well, but this is now in testing now that the Python rebuild has moved on. Please let me know (good and bad) how things are going with it so I can move it along to [extra]. Long-term, this probably needs some packaging love so pg_upgrade is actually usable on Arch, but that has not happened yet so you will require the old-school dump/reload with these. If anyone wants to undertake this project and get this into a state where it is possible to use pg_upgrade you are more than welcome to contribute patches and such for the build and whatever else we have to do. -Dan
