Log message:
    Simplify timezone-handling code per proposal to pghackers: get rid of
    setting timezone-related variables during transaction start.  They were
    not used anyway in platforms that HAVE_TM_ZONE or HAVE_INT_TIMEZONE,
    which it appears is *all* the platforms we are currently supporting.
    For platforms that have neither, we now only support UTC or numeric-
    offset-from-UTC timezones.
