Release date: 2008-06-12
This release contains one serious and one minor bug fix over 8.2.8. For information about new features in the 8.2 major release, see Section E.217.
A dump/restore is not required for those running 8.2.X. However, if you are upgrading from a version earlier than 8.2.7, see Section E.210.
      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.
