Description:

When trying to drop a schema using DROP SCHEMA "brokenSchema"; 

I'm facing the following error:
requested object address for unsupported object class 2: text result ""

The schema is empty from any table, type, trigger...

I haven't found any reference to this error on the internet.

Thanks a lot,
Charles
