A materialized view in PostgreSQL is a database object that stores the result of a query physically. It improves performance by precomputing and storing complex query results. To create a materialized view, use `CREATE MATERIALIZED VIEW view_name AS SELECT ...;`. You can refresh the view to update its data with `REFRESH MATERIALIZED VIEW view_name;`. This is useful for scenarios where query performance is critical, and the underlying data doesn’t change frequently.
