<title>Migration to Version 7.4.21</title>

A dump/restore is not required for those running 7.4.X.
However, if you are upgrading from a version earlier than 7.4.11,
see the release notes for 7.4.11.

Make <function>pg_get_ruledef()</> parenthesize negative constants (Tom)
</para>
<para>
Before this fix, a negative constant in a view or rule might be dumped
as, say, <literal>-42::integer</>, which is subtly incorrect: it should
be <literal>(-42)::integer</> due to operator precedence rules.
Usually this would make little difference, but it could interact with
another recent patch to cause
<productname>PostgreSQL</> to reject what had been a valid
<command>SELECT DISTINCT</> view query. Since this could result in
<application>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.
