Julian Hyde commented on CALCITE-5687:
--------------------------------------
Because {{getTable(String name, boolean caseSensitive) }} doesn't rely on
{{getTableNames}}, that means more work for the person implementing a subclass
of {{Schema}}, and more opportunity for inconsistency in the implementation.
It's not a goal to add 'convenience methods' to {{Schema}}; we have
{{SchemaPlus}} for that.
