I have never had this particular problem in PostgreSQL, it seems to
just know when queries can be flattened and indexes used. I know
that takes tons of work. Thank you for that.
Here's the Oracle question.

Hi all,
Is it possible to create an index on a view?

No, you can only create an index on the underlying tables. A view is a
virtual realtion, not a physical one, so what would the index point to?
Any functionality you need you should be able to get with functional
indexes.
Perhaps if/when postgresql gets materialized views an index on a view

Querying a view should use indexes if the underlying tables have
indexes and the planner can figure out how to use them. For complex
queries you might need to use a materialized

doesn't have materialized views per se but it does have functionality

Can you tell me what you mean by that?
