I tried to restore the sequence also by specifying it in the -t flag but got the same error. Can you explain why it isn't appearing in the plain text backup but it does appear in the output of pg_restore -l ?

You have to restore the sequence as well:

pg_restore -t specific_table -t specific_table_id_seq ...

Well, it isn't called "specific", is it?
