Since the encoding conversion now looks up database, it must be
done within a transaction. Currently the encoding conversion function
pg_client_to_server() is called in pq_getstr(), which may not be in a
transaction. So I would like to move the call to pg_client_to_server()
within pg_exec_query_string(), after start_xact_command() gets called.
Comments?
