phpmyadmin/pdf_schema.php3
Mike Beck 6b53a1c9a3 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)
