Release date: 2008-06-12
This release contains one serious and one minor bug fix over 8.3.2. For information about new features in the 8.3 major release, see Section E.198.
A dump/restore is not required for those running 8.3.X. However, if you are upgrading from a version earlier than 8.3.1, see Section E.197.
negative constants (Tom)
Before this fix, a negative constant in a view or rule might be
dumped as, say,
-42::integer, which is
subtly incorrect: it should be
(-42)::integer due to operator precedence rules.
Usually this would make little difference, but it could interact
with another recent patch to cause PostgreSQL to reject what had been a valid
SELECT DISTINCT view query. Since this
could result in pg_dump output
failing to reload, it is being treated as a high-priority fix. The
only released versions in which dump output is actually incorrect
are 8.3.1 and 8.2.7.
ALTER AGGREGATE ... OWNER TO
This oversight could lead to problems if the aggregate was later
involved in a
DROP OWNED or
REASSIGN OWNED operation.
