Hello all, when I try to access the system-table "pg_class", I get the following error: zeda=# select * from pg_class; NOTICE: get_groname: group 1 not found pqReadData() -- backend closed the channel unexpectedly. This probably means the backend terminated abnormally before or while processing the request. The connection to the server was lost. Attempting reset: Failed. !# What happened? Is there any way to repare the damaged table? Thanks in advance for all of you, who spend their valuable time!
