BTW unfortunately timestamptz is not recognized in PG 7.2. This is a minor but nagging instance of backwards compatibility being broken by PG 7.3.
Which remind me ... I bet the work that was done to get 4.6 to install under PG 7.3 totally ignored the timestamp/timestamptz issues. I bet none of the time manipulation code in acs-reference works unless the datamodel is modified to use timestamptz.
Someone's going to have to sit down and evaluate the impact of timestamp no longer carrying timezone information before we support PG 7.3. We may be stuck dropping PG 7.2 support for 4.7.
