I'd like to support arbitrary operators in variant. I did initial
testing and it looked like I was getting an OpExpr in fn_expr, but I
think that's because I was using a real table to test with. When I do
something like 'a' < 'b' it looks like the operator gets written out of
the plan. If that's indeed what's happening is there a hook I could use
to change that behavior?
