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
