Hi ,
Make sure no one is connected to the database while doing the back up. Usually memory alloc error comes if its a bad RAM .
check the pg_dump version and your database version match (this could be a guess)
try file level backup and restore into new database.

We are using postgresql version 8.1 and our database size is 7gb. Ram Size is 2 GB.
while trying to take backup through pg_dump i am getting following error.
oka97: pg_dump amtdb > amtdb.out
pg_dump: ERROR: invalid memory alloc request size 4294967293
pg_dump: SQL command to dump the contents of table "atbs2_logs" failed: PQendcopy() failed.
pg_dump: Error message from server: ERROR: invalid memory alloc request size 4294967293
pg_dump: The command was: COPY public.atbs2_logs (sno, request_time, msisdn, phone_make, error_code, error_desc, reply_message, request_query, responce_time, request_type) TO stdout;
When I tried to take a single table backup i.e is mentioned in the error named "public.atbs2_logs" then again getting following error.
pg_dump: SQL command failed
pg_dump: Error message from server: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
pg_dump: The command was: FETCH 100 FROM _pg_dump_cursor
So we are unable to take backup , we have tried the vacuum and reindex but not of any use.
Kindly help us Any help would be highly appreciate. Thanx in Advance.
