It is certainly possible to implement Materialized Views in PostgreSQL -- we
are using them for RedWeek.com right now. I wrote a page about the
experience, and I am currently working with a version 2 of the document.

As far as a "CREATE MATERIALIZED VIEW" syntax, and generic functions to do
any MV, those don't exist and probably won't in time for 7.5.
