Remove unstable KNN SP-GiST test

akorotkov · akorotkov · commit f5f084fc3ec5 · 2019-09-20T01:51:05.000+03:00
6cae9d2 introduced test for NULL values in KNN SP-GiST. This test relies on undetermined ordering showing different results on various platforms. This commit removes that test. Will be replaced with better test later. Discussion: https://postgr.es/m/6d51305e1159241cabee132f7efc7eff%40xs4all.nl Backpatch-through: 12
