MULE_INTERNAL
The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/11/multibyte.html
Description:
The documentation says that UTF-8 can be converted to any encoding:
UTF8 all supported encodings
That's not true:
db => SET CLIENT_ENCODING TO 'MULE_INTERNAL';
ERROR: invalid value for parameter "client_encoding": "MULE_INTERNAL"
DETAIL: Conversion between MULE_INTERNAL and UTF8 is not supported.
Maybe MULE shouldn't be a supported encoding.

One of the advantages of using MULE_INTERNAL as a database encoding
is, it allows a round trip conversion between encodings, plus speed
(unlike to/from UTF-8 conversion no table lookup is involved with
MULE_INTERNAL.)
On the other hand, UTF-8 does not allow round trip encoding
conversions for some encodings, which means you may loose some
information in your text data when you store it into a database.
