I've used "timestamptz" instead of "timestamp with timezone" because the PL/pgSQL parser doesn't seem to accept "timestamp with timezone" in all cases. At least I couldn't figure it out and being in a hurry settled on "timestamptz" since that was a change I could script that worked everywhere.
In this context it shouldn't matter though (did someone change it back from "timestamptz" to "timestamp with timezone" after I changed it??? If so, why???)
