   Hi @tdunning.  This PR includes an update of t-digest from 3.2 to 3.3 and I think that has caused a unit test of metastore statistics to fail with
   ```
   Error:  Failures: 
   Error:    TestAnalyze.testHistogramWithDataTypes1:501 Did not find expected pattern in plan: Filter\(condition.*\).*rowcount = 676.*,.*
   ```
   , where what's changed is the row count estimate for the results of an integer inequality predicate `store_id < 15` which has gone from 676 to 699.  Have some approximate stats computed by t-digest shifted in this version, e.g. an accuracy improvement?  If so, and this is expected, then I'll update the unit test's expectations accordingly...
