> madpack upgrade from 1.7.1->1.9 failed with the following message:
> {code}
> madpack.py : INFO : Testing PL/Python environment...
> madpack.py : INFO : > PL/Python environment OK (version: 2.6.2)
> madpack.py : INFO : Upgrading MADlib into MADLIB schema...

> madpack.py : ERROR : SQL command failed:
> SQL: DROP TYPE IF EXISTS madlib.svm_model_rec
> ERROR: cannot drop type madlib.svm_model_rec because other objects depend on
> it
> HINT: Use DROP ... CASCADE to drop the dependent objects too.
>
> Exception:
> (<type 'exceptions.Exception'>, Exception(), <traceback object at 0xe4c2d8>)
> madpack.py : ERROR : MADlib upgrade failed.
> {code}
> I believe this error would happen on 1.7.1->1.9.1 and perhaps other cases as
> well.
> Please investigate and fix this bug, and also determine what madpack changes
> are required in the future to avoid this problem.
