Drop/recreate for upgrade

If pgrx #121 is resolved, the need to DROP EXTENSION pgdd; CREATE EXTENSION pgdd; would go away. In that case, we need to be aware of the need to adjust for DDL changes made in src/lib.rs in version-to-version upgrade (e.g. sql/pgdd-0.3.1--0.4.0.sql).

Those scenarios may need review depending on if pgrx #120 is also resolved or not.

As it stands, drop/create is the upgrade path.
