Обсуждение: pgsql: Update time zone data files to tzdata release 2025b.

Update time zone data files to tzdata release 2025b.

DST law changes in Chile: there is a new time zone America/Coyhaique
for Chile's Aysén Region, to account for it changing to UTC-03
year-round and thus diverging from America/Santiago.

Historical corrections for Iran.
