missing database upgrade scripts in Evergreen 2.3.4

I think this makes a good argument for NOT allowing database changes after a release is made. IMNSHO, database changes should be something that is only done between minor releases and not for bug fixes. Bug fixes that require database changes should not be backported.

I think we seriously need to look at our support policy. I don't think the community is large enough to adequately support the number of releases that we currently do. I don't know how many times I've tried to help people with upgrade script issues in IRC.

Well, I've said this in IRC and I'll repeat it here. We currently have two streams of upgrade scripts: 1) the numbered scripts for individual DB patches and 2) the monolithic version-to-version upgrade scripts. I propose that we use the numbered scripts in a more robust way. Rather than copying and pasting their contents into a large script that can only run in a single thread (I realize the multithreaded postgres is available in 9.2), it would make more sense to have the version-to-version scripts basically have "include" statements (using that metaphorically) that would refer to the numbered scripts, allowing admins to break up parts of the upgrade to run concurrently. Moving to that would also require a knowledge of prerequisites for each numbered script. There may be valid technical reasons why that wouldn't be possible, but it seems that the upgrade dependency tracking has moved in that direction and it might just be time to commit to that direction.

I'm willing to help do that however I can.

There does not appear to be a change to the database from 2.3.3 to 2.3.4, which might cause confusion, because the pattern is broken.

Hi Wolf, we have stub upgrade scripts for 2.3.3-to-2.3.4 and 2.2.5-to-2.2.6 as of the Evergreen 2.3.5 release.

I've pushed working => user/berick/lp1134331-2.3-missing-upgrade-scripts

It back-ports scripts for 2.2.2-2.2.3and 2.2.3-2.2.4 into the rel_2_3 series.

Looks good. Picked to rel_2_3 series and set for the next point release. Thanks all!
