aha! that's not what you posted last time. you appended 'not null
default false'; which inexplicably breaks the ALTER.
try this:
ALTER TABLE a ADD COLUMN even_more_stuff text not null;
ALTER TABLE a ALTER even_more_stuff set default false;
ALTER TABLE a DROP COLUMN even_more_stuff;
ALTER TABLE a ADD COLUMN even_more_stuff boolean not null default false;
(this really looks like a bug in postgres, cc-ing to bugs)
