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.199.
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.198.
Make pg_get_ruledef() parenthesize 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.
Make ALTER AGGREGATE ... OWNER TO update
pg_shdepend (Tom)
This oversight could lead to problems if the aggregate was later
involved in a DROP OWNED or REASSIGN OWNED
operation.
