Jira issue: CRDB-68366

Start with sql/stats.TestCacheAutoRefresh and the failing query at stats_cache_test.go:878; inspect the captured test logs at outputs.zip/logTestCacheAutoRefresh4042064625 and the test_server_shim.go notes. Reproduce with the reported race configuration, then determine why CREATE STATISTICS is canceled and leave the test passing reliably.
