Nothing about the row itself changes when the underlying tables mutate underneath it — a sales dashboard or a cached report join keeps returning last week's numbers with the same confidence as this morning's, and a plain <code>SELECT * FROM</code> the view never flags the difference. <a href="https://www.postgresql.org/docs/current/view-pg-matviews.html">pg_matviews</a> is where that gap gets closed: a system view that lists every materialized view in the current database with its population state, index coverage, and defining query, one row per view.</p>
