If we compare the following two problems:
A. With glibc or ICU, every text index, including primary keys, are
highly vulnerable to inconsistencies after an OS upgrade, even if
there's no Postgres upgrade; vs.
B. With the builtin provider, only expression indexes and a few other
things are vulnerable, only during a major version upgrade, and mostly
(but not entirely) when using recently-assigned Cased letters.
To me, problem A seems about 100 times worse than B almost any way I
can imagine measuring it: number of objects vulnerable, severity of the
problem when it does happen, likelihood of a vulnerable object having
an actual problem, etc. If you disagree, I'd like to hear more.
