restoring table

Dear Team,

Postgresql Version:8.4

I could not restore a table (4.1GB) in postgresql database server.

This is the command I used to take table dump,

pg_dump databasename -t tablename --format plain --data-only >
~/backup.sql

Restore command

psql -U username -d databasename -f backup.sql

I am getting below error,
