Subject: Repair two TIME WITH TIME ZONE bugs found by Dennis Vshivkov.  Comparison
X-Git-Tag: REL7_2_8~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9524c6b8aedecfcea77287b4f6452288dcf8dc7a;p=thirdparty%2Fpostgresql.git

Repair two TIME WITH TIME ZONE bugs found by Dennis Vshivkov.  Comparison
of timetz values misbehaved in --enable-integer-datetime cases, and
EXTRACT(EPOCH) subtracted the zone instead of adding it in all cases.
Backpatch to all supported releases (except --enable-integer-datetime code
does not exist in 7.2).
