DROP CASCADE

Hi
I encountered something that puzzled me a bit.
Is it expected that DROP table CASCADE drops this table and just the
foreign key constraints but not the refering tables?

Hi Andreas,
yes, it is expected, at least according to the documentation: http://www.postgresql.org/docs/9.1/static/ddl-depend.html 

"In this case, it doesn't remove the orders table, it only removes the foreign key constraint."
