I need to do a file backup for each account_id.

Example:

COPY 
(
SELECT * FROM backup_table WHERE id = 1112 AND status = 1
) 
TO '/var/lib/pgsql/1112.sql';

COPY generates CSV and similar formats, not .sql.   only pg_dump, the command line utility, outputs .SQL

begin

      FOR crtRow in execute 'select account_id from backup_table WHERE migrated = 1 AND account_id = '|| $1

      LOOP

    COPY

        (SELECT * FROM gorfs.WBP_4868_backup_table_BLOBS WHERE migrated = 1 AND account_id = crtRow.account_id)

    TO '/var/lib/pgsql/gorfs_backup/%s.sql';

    end loop;

    return integer;

end

try...

begin

      FOR crtRow in
            select account_id from backup_table WHERE migrated = 1 AND account_id in $1

      LOOP

    COPY

        (SELECT * FROM gorfs.WBP_4868_backup_table_BLOBS WHERE migrated = 1 AND account_id = crtRow.account_id)

    TO '/var/lib/pgsql/gorfs_backup/' || crtRow.account_id || '.csv';

    end loop;

    return integer;

end

but you can't exactly return 'integer' if its a list of values, so I'm not sure what it is you want to return from this function...
