Thread: pgsql: Suppress variable-set-but-not-used warning from clang 13.
Suppress variable-set-but-not-used warning from clang 13. In the normal configuration where GEQO_DEBUG isn't defined, recent clang versions have started to complain that geqo_main.c accumulates the edge_failures count but never does anything with it. As a minimal back-patchable fix, insert a void cast to silence this warning. (I'd speculated about ripping out the GEQO_DEBUG logic altogether, but I don't think we'd wish to back-patch that.) Per recently-established project policy, this is a candidate for back-patching into out-of-support branches: it suppresses an annoying compiler warning but changes no behavior. Hence, back-patch all the way to 9.2.
