How to find all of the tables that are used in a view in Redshift?

Question

I'm trying to find a way of finding all of the tables that are used by a particular view in a list. Is there a Redshift Table/a query that I could run that I could use to find this information? I want to be able to insert the name of a view, and have all the tables used in this view returned as the output. Thank you.

There's no direct, supported mechanism to do this.

I do it by getting the SQL of the view from pg_views and then parsing it using pglast (a Python module) and from that, extracting the table and views names used by the view.
