[HACKERS] Patches that don't apply or don't compile: 2017-09-12 - Mailing list pgsql-hackers

Hello, hackers!

Thanks to the work of Thomas Munro now we have a CI for the patches on
the commitfest [1]. Naturally there is still room for improvement, but
in any case it's much, much better than nothing.

After a short discussion [2] we agreed (or at least no one objected) to
determine the patches that don't apply / don't compile / don't pass
regression tests and have "Needs Review" status, change the status of
these patches to "Waiting on Author" and write a report (this one) with
a CC to the authors. As all we know, we are short on reviewers and this
action will save them a lot of time. Here [3] you can find a script I've
been using to find such patches.

I rechecked the list manually and did my best to exclude the patches
that were updated recently or that depend on other patches. However
there still a chance that your patch got to the list by a mistake. In
this case please let me know.

Unless there are any objections I'm going to re-run this script once or
twice a week during the commitfest and write reports like this one.

Here is the list:
