I'm confused.
What do you mean by BE? BE's encoding is determined by the database
that FE chooses. If you just want to know what kind encodings are
there in the database, why not use:
SELECT DISTINCT ON (encoding) pg_encoding_to_char(encoding) AS
encoding FROM pg_database;
Also, FE's encoding could be any valid encoding that FE chooses,
i.e. it' not BE's choice.
Can you show me more concrete examples showing what you actually want
to do?

Wao. If pgAdmin could not display multibyte chars, all discussions
here are meaningless:-<
