title: Is it possible to partially refresh a materialized view in PostgreSQL?
body: <p><a href="https://stackoverflow.com/q/1783308/1801588">In Oracle, it is possible to refresh just part of the data</a>. But in PostgreSQL, materialized views are supported since 9.3 (the current version now), which is not so long. So I wonder: is it possible to refresh just part of the data in the materialized view in PostgreSQL 9.3? If yes, how to do it?</p>
