Hello All,
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.
It seems to me that you have corrupted data in that table for some
reason, perhaps bad hardware? I bet that a simple "SELECT * FROM
atbs2_logs" will fail as well.
Which server version is this exactly? 8.1.what?
How far did the pg_dump get before the crash? Is there any output at all?
