People can always pull from the git repo:

git://git.postgresql.org/git/users/kgrittn/postgres.git

Also, I can post a patch against HEAD at any time. Should I post
one now, and then again after this is solved?

Full disclosure requires that I mention that while Dan has completed
code to fix the page split/combine issues Heikki raised, I don't
think he's done testing it. (It's hard to test because you don't
hit the problem unless you have a page split or combine right at the
point where the hash table for predicate lock becomes full.) So,
anyway, there could possibly be some wet paint there.
