commitfest app

I haven't paid much attention to the new commitfest app until now.
Generally, it looks good, but I'm wondering if we should have a
"committer" field.

I'm thinking of picking up at least the following items if/when they are
ready, but such a thing might help us to make sure we don't trip over
each other.

DROP COLUMN/CONSTRAINT IF EXISTS support

COPY WITH CSV FORCE QUOTE *
<https://commitfest.postgresql.org/action/patch_view?id=93&gt;
hstore enhancements
<https://commitfest.postgresql.org/action/patch_view?id=122&gt;

cheers
