I blogged yesterday about how I had not noticed that the File Text Array FDW had got out of date. This is exactly the sort of problem that the buildfarm was created to detect. So naturally I decided not to allow that to happen any more. I built a simple module for the buildfarm like this, added the name of the module to my buildfarm config, and now there will be an error any time the extension doesn't build or test right.. You can see a sample of a buildfarm run with this testing here
So now I'm going to fix the File Fixed Length FDW, and of course I'll create a testing module for it too.
