Subject: Suppress uninitialized-variable warning in guc.c.
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=60ca4eec8dc7569e267844aac302174a9ec14801;p=thirdparty%2Fpostgresql.git

Suppress uninitialized-variable warning in guc.c.

Back-patch 26812bcaa into 9.5, to suppress one more warning
in out-of-support branches.  (Doesn't appear to be needed
before 9.5.)
