No, I was complaining that a hook right there is useless and expensive.
transformExpr() is executed multiple times per query, potentially a very
large number of times per query; so even testing to see if a hook exists
is not a negligible cost. And I have not seen anything I regard as a
convincing demonstration of use-case that can't be handled as well or
better in some other way.
