Restoring 2 Tables From All Databases Backup

Dear all,

About 1 month ago, I take a complete databases backup of my Database
server through pg_dumpall command.
Today I need to extract or restore only 2 tables in a database.

Is it possible or I have to restore complete Databases again. Size of
backup is 10 GB in .sql.gz format.

Please let me know how to extract the tables from this 10Gb backup file


Thanks
