</span>Hi Alessandro,<br>
probably not, we do not have inherited tables and we have autovacuum<br>
activated. St_estimated_extent is correctly called when loading postgis<br>
tables. The matter is that we use very few table, but mainly views and<br>
materialized views. Postgres does not collect metadatas on views:<br>
See <a href="https://trac.osgeo.org/postgis/ticket/510" rel="noreferrer" target="_blank">https://trac.osgeo.org/postgis/ticket/510</a><br>
Having that would be a great improvement. I would be avalaible for funding.<br>
I already asked to postgres community and had no feedback.. maybe I asked<br>
the wrong place.<br></blockquote><div><br></div><div>The answer from strk makes sense to me, I might be wrong but calculating estimated metadata on a query doesn't make much sense to me.<br><br><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Any idea concerning multithreading configuration?<br>
