Attaching a support function to a SQL-language function seems pretty
weird to me. I think probably what is happening is that the SQL
function is getting inlined and thus there is nothing left to apply
the selectivity hook to. simplify_function() will try the
SupportRequestSimplify hook before it tries inlining, so the fact
that that one registers isn't at odds with this theory.
