From 340536dd489286d0f98878843390d92ddc593be0 Mon Sep 17 00:00:00 2001 From: Alexander Korotkov Date: Fri, 20 Sep 2019 01:46:49 +0300 Subject: [PATCH] Remove unstable KNN SP-GiST test 6cae9d2c10 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.
