E.28. Release 8.0.17
Release date
This release contains one serious bug fix over 8.0.16. For
information about new features in the 8.0 major release, see
Section E.45, « Version
8.0 ».
E.28.1. Migration to Version 8.0.17
A dump/restore is not required for those running 8.0.X.
However, if you are upgrading from a version earlier than
8.0.6, see the release notes for 8.0.6.
E.28.2. Changes
-
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.
