I've committed patches to do the following: o Support AT TIME ZONE date/time syntax. o Fix INTERVAL mixed-sign output representation. "ISO format" has changed a little, and no longer uses the "AGO" qualifier but instead uses signed numbers. o Allow functions called with untyped constant strings to fall back to a string type if available. Previously, PostgreSQL refused to chose between types from different categories (e.g. string vs numeric). o Add tests for OUTER JOIN syntax to the regression test. Needs more work. Since a couple of functions were added to pg_proc, an initdb is required (sorry!). - Thomas
