Fwd: Views "missing" from information_schema.view_table_usage

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!

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.
