[Feature] Can drop tables, (drop, change size, data type of columns), and views used in views - this is a arguably a misfeature but sometimes it comes in handy when you are an EXPERT user :) [MySQL 5.1] Yes - yikes! [PostgreSQL 8.4] No [Microsoft SQL Server 2008] 
Yes - (but if you schema bind your tables and views, you can not drop dependent objects so this does appear to be the best of both worlds)
