Replace a materialized view in Postgres I have a materialized view in Postgres 9.3 that I'd like to update with new columns. However, other materialized views also depend upon this view, and the error message indicates that dropping a view isn't possible when other objects depend on it.  


  ERROR:  cannot drop materialized view latest_charges because other objects depend on it


It also appears from the documentation that the REPLACE keyword isn't valid for a materialized view.  Is there any shortcut aside from dropping all dependent objects and rebuilding each one?
As of PostgreSQL 9.4: Different to the documentation of CREATE VIEW, the documentation of CREATE MATERIALIZED VIEW does NOT mention the REPLACE keyword. There seems to be no shortcut aside from dropping all dependent objects and rebuilding each one.

When you do so, I can only recommend two small things:


Use DROP MATERIALIZED VIEW blabla CASCADE to get a list of all dependent objects
Do the drop and recreation of all dependent object in one transaction.
