I found new bug in command/variable.c in parse_client_encoding(), nobody probably never see this error: if (pg_set_client_encoding(encoding)) { elog(ERROR, "Conversion between %s and %s is not supported", value, GetDatabaseEncodingName()); } because pg_set_client_encoding() returns -1 for error and 0 as true. It's fixed too. IMHO it can be apply.
