Removing it is the wrong solution.
The idea of renaming it to char1 might be an appropriate balance of pain
versus benefit. Or perhaps not; I'd want to see a proposed patch before
committing to doing anything here.

That's a pipe dream. You can't use enums in catalogs that underlie the
enum implementation. Possibly you could kluge something so that there
are phony entries in pg_enum reflecting the hard-wired values that the C
code uses, but I entirely fail to see any point in such a thing.
