Oh, I see. That's fine with me. From the source code it's hard to see
when a SQL-callable function is only there to implement an operator,
though (and it seems a bit far-fetched to suppose that the developer
will think, upon seeing an undocumented function, "oh this must
implement some operator, I will look it up at pg_proc.h").
I think the operator(s) should be mentioned in the comment on top of the
function.
