Subject: Suppress compiler warning about potentially uninitialized variable.
X-Git-Tag: REL9_2_BETA1~1470
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=426cafc46c8bf5aeda38e8d17f1d86a48e627e43;p=thirdparty%2Fpostgresql.git

Suppress compiler warning about potentially uninitialized variable.

Maybe some compilers are smart enough to not complain about the previous
coding ... but mine isn't.
