Having looked at it, I don't like the patch as-is; it misses
timestamptz_recv and doesn't handle the boundary condition
correctly for the HasCTZSet case. However the details of the latter
are likely to change completely once we finish adopting src/timezone.
I'll make a note to do something with this issue after the TZ patch
is in.
