What I think we'd need to have a complete solution is
convert(text, name) returns bytea
-- convert from DB encoding to arbitrary encoding
convert(bytea, name, name) returns bytea
-- convert between any two encodings
convert(bytea, name) returns text
-- convert from arbitrary encoding to DB encoding
The second and third would need to do a verify step before
converting, of course.
Is there any reason these functions shouldn't be marked immutable? Also,
I'm wondering if we should give them disambiguating names, rather than
call them all convert.
