The last commit that can be seen at https://git.postgresql.org/gitweb/?p=postgresql.git is about 18 hours old, but there have been several commits to gitmaster since then. This is also blocking the buildfarm from seeing that it has work to do.
Hrrk. That's probably my fault, as I did a small upgrade on it earlier today. (Which also broke commit messages, but those got fixed, I bleieve)
I'm in transit right now, but I'll take a look at it later tonight unless one of my infra team colleagues beats me to it.
