The fastest thing to do if you really want to get rid of everything is
do delete from for each of the tables starting with the ones that don't
have any tables dependent on them.
Another thing to note is that postgres doesn't automatically create
an index on columns that reference another table. When you are taking
advantage of cascading deletes you normally will want an index on such
columns. If you insist upon being able to do the delete using just a delete
from table1 you will want to create these indexes.
