------------------------------------------
Hi [~julianhyde]. Thanks for the review.
Regarding {{RelOptRulesTest.xml}}, I didn't add anything to it in this PR.
Perhaps the comment relates https://issues.apache.org/jira/browse/CALCITE-4515.
I was not aware that there are any problems with it.

> Consider the query {{DROP TABLE s.t}}. The {{ServerDdlExecutor}} will attempt
> to resolve the default schema path, and the would try to invoke
> {{SqlIdentifier.getSimple}} on the {{s.t}} identifier. When assertions are
> enabled this would lead to an AssertionError. When assertions are disabled
> this would lead to an incorrectly resolved table name: {{s}} instead of {{t}}.
> All {{DROP}} commands are affected.
