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   <https://commitfest.postgresql.org/action/patch_view?id=89>   COPY WITH
CSVFORCE QUOTE *   <https://commitfest.postgresql.org/action/patch_view?id=93>   hstore enhancements
