Huh, that is very interesting. On my MacBook with a
build using --with-system-tzdata=/usr/share/zoneinfo,
I get:
postgres=# select * from pg_timezone_names where name ilike '%dublin%';
name | abbrev | utc_offset | is_dst
---------------+--------+------------+--------
Europe/Dublin | IST | 01:00:00 | t
(1 row)
and the same on a RHEL box. However, if I build using
PG's internal copy of the timezone database:
regression=# select * from pg_timezone_names where name ilike '%dublin%';
name | abbrev | utc_offset | is_dst
---------------+--------+------------+--------
Europe/Dublin | IST | 01:00:00 | f
(1 row)
We're all on 2024a (and Europe/Dublin hasn't changed definition
recently anyway), so what's going on there?
I suspect this may be down to different options being used in
the "zic" run that builds the zone data files, but haven't
had time to look closer than that.
