Thomas Munro recently put together a page that shows a summary of the buildfarm builds for the tip of each branch. That looked neat to me, but rather than scraping data from the web interface, it seemed to me that it would be better done in the buildfarm server itself, with data drawn direct from the database. The only problem with this was that we haven't kept track of which commits are at the tip of each branch. But we do have that information ready, it's used by a script to build the branches_of_interest.json file each time there's a git commit. So I added a new table in the database, and modified that script to load the information into the table. Once we had that information in the database, making the new page was fairly simple. You can see it at https://buildfarm.postgresql.org/cgi-bin/show_summary.pl.
