another BUG

hello,

bd=> INSERT INTO pg_group VALUES('group-tgy');
bd=> \z
NOTICE: get_groname: group 87 not found
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
bd=> select * from pg_group;
PQsendQuery() -- There is no connection to the backend.
