Noch ein kleiner Tip, gerade auf der PostgreSQL Hackers ML gesehen:

Yes (and no :) Unix system time goes from ~1902 to ~2038, and the time
zone database included with your system can only work in that range.
So I use system routines for dates within that range and bypass those
(and do not assign time zones) outside that range.

However, I'm puzzled as to why these checks don't seem to be effective
when using dates within this range. Will look at it, and post patches.

Thanks for the report.
