Subject: Silence compiler warnings about possibly unset variables.
X-Git-Tag: REL9_4_BETA1~583
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=120c5cc761e0d99a9a2f3349f4031850b0dbd5a0;p=postgresql

Silence compiler warnings about possibly unset variables.

They are in fact set in every case where they are needed, but the
compiler doesn't know that.

Per gripe from Tom Lane.
