This has been discussed before:

The magic pg_enc2iananame_tbl[] you reference in your patch does not exist,
and if it did exist it wouldn't work on all platforms, since encoding
names aren't sufficiently well standardized :-(

I'm quite unconvinced that that's a bug.  If we tried to do a conversion
here, it would be trivial to set up denials of service for logging ---
just include a character in a comment in your SQL command that cannot be
converted to the LC_MESSAGES character set.
