Subject: Silence compiler warning about variable being used uninitialized.
X-Git-Tag: REL9_5_ALPHA1~1179
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f464042161fb980578c33fedc2742c5a4d941fa2;p=postgresql

Silence compiler warning about variable being used uninitialized.

It's a false positive - the variable is only used when 'onleft' is true,
and it is initialized in that case. But the compiler doesn't necessarily
see that.
