Hello List I am using postgresql 7.4.7 in a voip production setup. I have been using pg_dump -Fc for regular backing up. Since yesterday i am getting the following error for the command: root# pg_dump -h 'localhost' voipdb -t voipcall -Fc -f voipcall.bak The error is : pg_dump: ERROR: invalid memory alloc request size 4294967293 pg_dump: SQL command to dump the contents of table "voipcall" failed: PQendcopy() failed. pg_dump: Error message from server: ERROR: invalid memory alloc request size 4294967293 pg_dump: The command was: COPY public.voipcall (id, accountid, .........., prefix) TO stdout; However when i tried to Vacuum analyze the same table its fine and no errors. Also the SQL access to the same table runs fine without any errors. Only the pg_dump is failing for this particular table. Can anyone suggest a method to fix this? Thanks in advance Manjula __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
