We were setting extra_float_digits = 0 to avoid platform-dependent output in this test, but that's still able to expose platform-specific roundoff behavior in some new test cases added by commita3d284485, as reported by Peter Eisentraut. Reduce it to -1 to hide that. (Over in geometry.sql, we're using -3, which is an ancient decision dating to337f73b1b. I wonder whether that's overkill now. But there's probably little value in trying to change it.) Back-patch to v12 wherea3d284485came in; there's no evidence that we have any platform-dependent issues here before that.
