Can't upgrade from 2.0.1 to 2.1 with extensions

[robe]

I thought I had tested this, but guess not. This just effects extensions.

If I'm on 2.0.1 and I do this:

ALTER EXTENSION postgis UPDATE TO "2.1.0SVN";

I get "cannot drop type summarystats because extension postgis depends on it".

To get around these issues, I explicitly add these drop entries to

extensions\postgis\sql_bits\remove_from_extension.sql.in

Ideally it would be nice to have a single location for this so we don't have to state it twice, but for now I'll do the same for these dropped types.
