i was trying to back up db from the server.
i found the error while i was trying to backup.
bash$ /usr/local/pgsql/bin/pg_dumpall > db.out
ERROR: MemoryContextAlloc: invalid request size 4294967293
PQendcopy: resetting connection
SQL query to dump the contents of Table 't_oommain' did not execute correctly. After we read all the table contents from the backend, PQendcopy() failed. Explanation from backend: 'ERROR: MemoryContextAlloc: invalid request size 4294967293
'.
The query was: 'COPY "t_oommain" TO stdout;
'.
pg_dump failed on xenodb, exiting
what shall i do here?
please give me the solution for this problem.
Thank you very much.
