 MissingSchemaAction, GetSchemaTable should be called.
 And also, I don't notice that is called multiple times. Eventhough
 called, it is optimized at DataReader to cache that information.

+The attached patch demonstrates how to fill the DataSet without
+calling GetSchemaTable.  There aren't multiple calls to
+GetSchemaTable, but the implementation could have multiple queries
+(and does for Npgsql).  Please review the patch before dismissing this.
+The MS runtime does not rely on the implementation of the
+IDataReader.GetSchemaTable to know what columns belong in the DataSet.
