Hello,

I'd like to request the documentation be updated to add a note that the information_schema.view_table_usage view won't include views that query materialized views.  

Thanks!

Jon

Hi Erik - sorry I missed your reply when I replied to David's.  That is indeed the issue.  The object that the view is querying is a materialized view.  

Thanks for the link.

Is the one view you cannot find in view_table_usage a materialized view?
Because those are not covered by view_table_usage[1].
