There is no such feature in PostgreSQL (yet), so you'll have to
do it yourself.
The "materialized view" would then be a regular table (with read only
access), and each underlying table would have a trigger that records
changes with a timestamp to a log table.
You can then write a function that brings the "materialized view"
up to date.
