My position is basically that having TimeZone come out as 'UCT' rather
than 'UTC' (affecting no visible behavior of the timestamp types, AFAIK)
was not such a grave problem as to require violating community norms
to get it fixed in this week's releases rather than the next batch.
I hadn't had time to consider your patch last week because I was (a)
busy with release prep and (b) sick as a dog. I figured we could let
it slide and discuss it after the release work died down. I imagine
the reason you got zero other responses was that nobody else thought
it was of life-and-death urgency either.
Anyway, as I said already, my beef is not with the substance of the
patch but with failing to follow community process. One "yes" vote
and one "no" vote do not constitute consensus. You had no business
assuming that I would reverse the "no" vote.
regards, tom lane
