title: Gather statistics on materialized views as part of gather_schema_stats
body: <p>We use the following to refresh statistics for all tables in a given schema:</p>
  
  <pre><code>exec dbms_stats.gather_schema_stats(ownname =&gt; 'some_schema', estimate_percent =&gt; dbms_stats.auto_sample_size, cascade =&gt; true, method_opt =&gt; 'FOR ALL COLUMNS SIZE AUTO', degree =&gt; 12);
  </code></pre>
  
  <p>This however, sets row-counts for our materialized views to zero and has the unwanted side effect of causing inefficient query plans for queries against materialized views. We work around this by gathering table stats against the specific mviews after the schema stats have run.</p>
  
  <p>My question is: can I change the parameters to gather_schema_stats in any way that will cause mview row-counts not to be set to zero?</p>
