Had to remove the cascade_p feature of the new drop_type procedure, becauseimplementing it in Oracle would require a huge reorganization of the orderof definition of object and metadata tables and their associated tables,which just is not going to happen.
Fixed bug in regard to types that require a "to_sql" option to workcorrectly. Removed Daveb's kludge to look for to_timestamp() directly.Fixed bugs in the test code, which was confusing the issue.
Believe it or not, "create_type" has never, ever checked to see if thegiven supertype is a valid type. The code now verifies that the givensupertype is a child of "acs_object", except when supertype is passed inas NULL or '' (in which case it's set to acs_object). Only did it forPostgreSQL since it's been around forever and whatever Oracle users don'tknow, won't hurt them.
