error postgresql 9.4 when dumping data

Question

I have error like at the picture when I dump the data. I change ssl_renegotiation_limit=0 but I have same error. I have error

pg_dump: Dumping the contents of table "tunggakan" Failed: PQgetCopyData failed.
pg_dump: The command was : COPY public.tunggakan(blabla,blaaa,blabla) to stdout; "

I use the following syntax:

pg_dump --host localhost --port 5432 --username "postgres" --format custom --blobs --verbose --file "/root/thecontent.backup" "table name"
