Can you elaborate, which patches you think were not ready? Let's make
sure to capture any concrete concerns in the Open Items list.

I agree the last-minute crunch felt more intense than in previous years.
I'm guilty myself; I crunched the "direct SSL" patches in. My rationale
for that one: It's been in a pretty settled state for a long time. There
hasn't been any particular concerns about the design or the
implementation. I haven't commit tit sooner because I was not
comfortable with the lack of tests, especially the libpq parts. So I
made a last minute dash to write the tests so that I'm comfortable with
it, and I restructured the commits so that the tests and refactorings
come first. The resulting code changes look the same they have for a
long time, and I didn't uncover any significant new issues while doing
that. I would not have felt comfortable committing it otherwise.

Yeah, I should have done that sooner, but realistically, there's nothing
like a looming deadline as a motivator. One idea to avoid the mad rush
in the future would be to make the feature freeze deadline more
progressive. For example:

April 1: If you are still working on a feature that you still want to
commit, you must explicitly flag it in the commitfest as "I plan to
commit this very soon".

April 4: You must give a short status update about anything that you
haven't committed yet, with an explanation of how you plan to proceed
with it.

April 5-8: Mandatory daily status updates, explicit approval by the
commitfest manager needed each day to continue working on it.

April 8: Hard feature freeze deadline

This would also give everyone more visibility, so that we're not all
surprised by the last minute flood of commits.
