Обсуждение: zic data updates
Current beta seems to have the 2006k version of the zic database. The current zic database is version 2006n however. Since this update does not include source code but just data files I would vote to do the update in beta, what do others think? One prominent update concerns Brazil which changes to summer time one week later this year (next weekend actually). Joachim

[ shrug... ] And by the time we release 8.2, it'll no doubt have
changed twice more. Folks who live in countries where DST rules change
with no notice will probably have to get used to downloading and
installing zic updates for themselves, because there's no chance that
our releases will be perfectly up to date.
For the Red Hat RPMs, I've been considering modifying the installed
file tree to link to /usr/share/zoneinfo so that Postgres would track
routine updates to the tzdata package automatically. This relies on
knowing that the system uses the same zic database format we do, and
where it keeps it, so I fear it's not a very portable answer :-(.
But there are definitely downsides as well as upsides to maintaining
our own timezone support.

Upgrade to a newer postgresql version is not the "right" answer though.

Separated projects have different directions sometimes so it's not worth the risk. -- Euler Taveira de Oliveira http://www.timbira.com/
