That command should give you the number of tables in your plain dump:

  grep "CREATE TABLE" your_dump_file | wc -l

If you have a binary dump (ie, tar or custom), you should do this:

  pg_restore -s your_dump_file | grep "CREATE TABLE" | wc -l

There's no easy way to get the number of tuples in each table.

notepad? :)

I mean, with a SQL file, this is just a bunch of SQL queries. So there's
no real way to check the file integrity without restoring it.

On a binary dump, you can do a "pg_restore your_dump_file > /dev/null".
It should warn you if you have an integrity issue.
