I am trying to backup a database products with pg_Dump. The total size of the database is 1.6 gb. One of the table in the database is product_image which is 1gb in size. When I run the pg_dump on the database the database backup fails with this error. ##pg_dump: Dumping the contents of table "product_image" failed: PQgetCopyData () failed. pg_dump: Error message from server: lost synchronization with server: got messag e type "d", length 6036499 pg_dump: The command was: COPY public.product_image (id, username, projectid, session, filename, filetype, filesize, filedata, uploadedon, "timestamp") T If I try to backup the database by excluding the product_image table, the backup succeeds. I tried increasing the shared_buffer in the postgres.conf to 1.5gb from 128MB , but the issue still persists. How can this issue be resolved? -- View this message in context: http://postgresql.nabble.com/pg-dump-Error-message-from-server-lost-synchronization-with-server-got-messag-e-type-d-tp5854831.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
