sed - How to restore a single table from a .sql postgresql backup?

A table's rows were mistakenly deleted from the database. We have a db backup which results in a sql file that can restored like so:

psql -h localhost -d proddump -f /Users/U/Desktop/prod_db_backup/PostgreSQL/site_prod.sql

This ends up doing a full restore locally. But what we need is to restore a single table's rows to production. Any tips on how to make this work with PostgreSQL 9.1?

Thanks

I'm not aware of any tool for this, but this one-liner extracts precious_table from my_backup.sql file:

sed -n '/^COPY precious_table /,/^\.$/p' my_backup.sql
