---------------------------------------------------------
A preferable behavior is: (IMHO)
1) if query for a single table that contains complex types we don't support
yet, gracefully error out with messages like "the table contains complex types
which is not supported"
2) if query with a pattern, we should return the tables that only contain types
we support and also a list of table names we don't support. Alternatively, we
can just put error tables in the log and only return good tables.
