This is the performance-list, and this is not a performance-related
question. Please use the pgsql-general or pgsql-novice list for this
kind of questions.

PostgreSQL should pick up the correct timezone from system
configuration. I don't know why that's not happening in your case, but
you can use the "timezone" parameter in postgresql.conf to set it
manually. See manual:

ALTER DATABASE foo SET TIMEZONE TO 'bla';

You can alter the template-database.

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.
