Wouldn't that drop table as well?  Like all the geometry tables people use that have geometry type?

Subject: [postgis-devel] New uninstall_postgis.sql script
Hi all,

I've just committed a new generated uninstall_postgis.sql script to 1.4 
which gives the complete SQL script required to remove all of the 
PostGIS functions/types/operators from a database. So please if you do 
add/change any functions types, please verify that you also update the 
install SQL script too.

At the moment, the script simply uses DROP TYPE ... CASCADE on the 
PostGIS types which removes them completely from the database; however 
it struck me that this could be a way of unifying our 
installation/removal/upgrade procedures since an upgrade process 
involves removing all of the old definitions and adding the new ones. 
Obviously this would only work with 1.4 onwards, but easier upgrades 
would put us in a great position going forwards. Thoughts?
