I attempted this in the attached v7. There are 4 new functions for
truncating timestamptz on an interval -- with and without origin, and
with and without time zone.
Parts of it are hackish, and need more work, but I think it's in
passable enough shape to get feedback on. The origin parameter logic
was designed with timestamps-without-time-zone in mind, and
retrofitting time zone on top of that was a bit messy. There might be
bugs.
