Not to put too fine a point on it: the project has advanced a long way
since you did that code. Our standards *should* be higher than they
were then.

We still haven't learned how to do it right, actually. I think the
history of the LIKE indexing problem is a perfect example of why fixes
that work for some people but not others don't survive long. We put out
several attempts at making it work reliably in non-ASCII locales, but
none of them have withstood the test of actual usage.

You forgot
* will the fix institutionalize user-visible behavior that will in the
long run be considered the wrong thing?
* will the fix contort new code that is written in the same vicinity,
thereby making it harder and harder to replace as time goes on?
The first of these is the core of my concern about %TYPE.
