Julian Hyde commented on CALCITE-4757:
--------------------------------------
When something is an Avatica problem but manifests in Calcite, as this case is,
it's definitely worthwhile adding tests in both projects.
In the past we have created "Update Calcite to Avatica version x.y" issues
whose PR adds new unit tests. See [Calcite PR
1259|https://github.com/apache/calcite/pull/1259] (linked to CALCITE-3116) for
example.
