I am a bit confused here. We have tinkered with LIKE indexing at least a
year. Now that a solution is found that *works*, it is claimed that it is
harmful because LIKE was doing the wrong thing in the first place. OTOH,
I have not seen anyone independently claim that LIKE is wrong, nor do I
see anyone proposing to actually change it. If we install my fix now we
have a system that works better than the previous release with no change
in semantics. If someone wants to change LIKE at a later point, reverting
my changes would be the least part of that work.
