It was. I don't think PG has ever accepted just "PST" (or "CDT") as a timezone name. There's no such entry in the IANA tz database, and it's not a legal POSIX zone specification --- you'd need at least "PST8" for it to go through that code path. I tried it just now on 7.4.30, which is the oldest version I have on this machine (about 2 years older than 9.2.0) and it failed as expected: regression=# set timezone = 'PST'; ERROR: unrecognized time zone name: "PST" Now, it's barely conceivable that you strong-armed 9.2 into accepting it by making a file or symlink named "PST" in the timezone database directory of the old installation ... but otherwise, I'm quite certain it would not have taken it. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
