That's the problem - it's not dropped with it.

Btw, if I do "ALTER EXTENSION pgq ADD SCHEMA pgq;" during
"CREATE EXTENSION pgq FROM 'unpackaged';" then Postgres
will complain:

  ERROR:  cannot add schema "pgq" to extension "pgq" because the schema
  contains the extension

Seems the code is pretty sure it's invalid concept...
