Release date: 2008-06-12
This release contains one serious and one minor bug fix over 8.1.12. For information about new features in the 8.1 major release, see Section E.247.
A dump/restore is not required for those running 8.1.X. However, if you are upgrading from a version earlier than 8.1.2, see Section E.245.
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.
