Review comment:
> Why share the table name between the in-memory and external catalog
but not the database?
I think you are right. I checked the
[jdbc](https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/connectors/table/jdbc/)
connector, we could specify a different jdbc table name when creating the
flink table. It make sense to allow both db & table name to be overridden.
