Back off output precision in circle.sql regression test.
We were setting extra_float_digits = 0 to avoid platform-dependentoutput in this test, but that's still able to expose platform-specificroundoff behavior in some new test cases added by commita3d2844,as reported by Peter Eisentraut. Reduce it to -1 to hide that.(Over in geometry.sql, we're using -3, which is an ancient decisiondating to337f73b. I wonder whether that's overkill now. Butthere's probably little value in trying to change it.)Back-patch to v12 wherea3d2844 came in; there's no evidence thatwe have any platform-dependent issues here before that.Discussion:https://postgr.es/m/15551268-e224-aa46-084a-124b64095ee3@2ndquadrant.com
