E.257.2. Changes

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)::integerdue 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 validSELECT DISTINCTview 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.
