Subject: Initialize variable to silence compiler warning.
X-Git-Tag: REL_12_BETA1~661
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5963b29e03d9b93011acb3954ccc3565d217acc3;p=postgresql

Initialize variable to silence compiler warning.

After ff11e7f4b9ae Tom's compiler warns about accessing a potentially
uninitialized rInfo. That's not actually possible, but it's
understandable the compiler would get this wrong. NULL initialize too.
