Here can't be used static default encoding as for DatabaseEncoding, because
typical code is
if (!ClientEncoding)
/* ...means "if user doesn't set itself client
* encoding by SET command"
*/
ClientEncoding = DatabaseEncoding;
and if you set anywhere before this as default
ClientEncoding = &pg_enc2name_tbl[ PG_SQL_ASCII ]; the ClientEncoding will
always TRUE and always SQL_ASCII and the only way is change it by 'SET
CLIENT_ENCODING' command. But we don't want it, wanted is after connection
set as default ClientEncoding same encoding as actual DabaseEncoding.
