FWIW, I noticed while fooling with pre-release Fedora 28 that gcc 8.0.1
emits a whole boatload of these warnings by default. This patch doesn't
seem to have moved the needle very much, either. In a quick look, it
seemed like a lot of them were things we simply wouldn't be interested
in fixing ("yeah, the path length limit is MAXPGPATH, tough"). So
I'm thinking we're going to be needing -Wno-format-truncation soon.
