My gut feeling is you'll run into insurmountable grammar-ambiguity
problems. I might be wrong, but I have an idea that this has
already been tried and failed on that point.
Inventing commutator operators for LIKE etc could be a path of
much less resistance (unless the operator names get bikeshedded
to death). Are there really that many that people need?
A quick query of pg_operator suggests that the LIKE/regex family
is the bulk of the problem for real-world cases.
