Subject: [PATCH] show pdf schema also if there are no relations (still only
 works if there are no relations at all if there are some tables that don't
 have relations  and some that do it is still not ok...) also now it checks if
 a page does have any tables in table_coords table though it will only die
 saying 'no tables' if it doesn't (i don't want to introd a new string now
 before 2.3.0 and this case shouldn't happen anyway)
