It works with encoding table (pg_enc2name_tbl) and it's compiled into backend and client too. It means number of
encodingis not possible change after compilation and you (user) can't add new encoding without pg_enc2name_tbl[]
change.I original thought we can add new encodingson-the-fly in 7.3 :-) You're right.
IMHO implement "User defined charsets(encodings)" will problem forcurrent libpq design.
