Yes, except if pg_get_encoding_from_locale() couldn't figure out what PG 
encoding LC_CTYPE corresponds to. We let CREATE DATABASE to go ahead in 
that case, trusting that the user knows what he's doing. I suppose we 
can extend that trust to this case too, and assume that the encoding of 
LC_CTYPE actually matches the database encoding.

Or if the encoding is UTF-8 and you're running on Windows, although on 
Windows we want to always call bind_textdomain_codeset(). Or if the 
database encoding is SQL_ASCII, although in that case we don't want to 
call bind_textdomain_codeset() either.
