Which "IST" are you interested in? Irish, Israel, or Indian Standard Time?
Postgres prefers to use the zic timezone names, which are less
ambiguous. Try this to see likely options:
regression=# select * from pg_timezone_names where abbrev = 'IST';
name | abbrev | utc_offset | is_dst
---------------+--------+------------+--------
Asia/Calcutta | IST | 05:30:00 | f
Asia/Colombo | IST | 05:30:00 | f
Europe/Dublin | IST | 01:00:00 | t
Eire | IST | 01:00:00 | t
(4 rows)
If you're after Indian Standard Time, set timezone to 'Asia/Calcutta'.
You'll probably also want to set timezone_abbreviations to 'India' so
that "IST" is interpreted the way you want in timestamp datatype input.
