Connection Error during Pg_restore

Hi there

I'm doing a restore of a large table. The backup file is 18gb. When I run
the restore after sometime it comes up with this error while it is restoring
the data.

pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 3022; 0 4287406059 TABLE
DATA tbl_exampletable postgres
pg_restore: [archiver (db)] COPY failed: server closed the connection
unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
WARNING: errors ignored on restore: 1

It will work if I use COPY but the table is so big I need to use pg_dump to
compress it.

Any help would be great.

Thanks

Rebecca
