I looked into this more, and I'm guessing the answer is "yes".<div><br></div><div>Looks like PostGIS 1.5.3 can be used with Postgres 9.1 beta.</div><div><br></div><div>I assume that the index used by Postgres has no bearing on how PostGIS performs. Is this true? However, it may not be true because Postgres will need additional support from PostGIS to handle GIST indexes on geometry objects?<div>

Will PostGIS have a release that supports Postgres 9.1 and the new GIST index when 9.1 comes out?<div><br></div><div><font color="#888888">Aren</font><div><div></div><div class="h5"><br><br><div class="gmail_quote">On Mon, Jul 25, 2011 at 2:34 PM, forkandwait <span dir="ltr"><<a href="mailto:forkandwait@gmail.com" target="_blank">forkandwait@gmail.com</a>></span> wrote:<br>

> Brent and Sean are correct. Nevertheless, it is worth noting that if you are<br>
trying to do k nearest neighbor queries, PostgreSQL 9.1 has much better (as in<br>
orders of magnitude) indexing support for this particular scenario.<br>
See <a href="http://www.depesz.com/index.php/2010/12/11/waiting-for-9-1-knngist/" target="_blank">http://www.depesz.com/index.php/2010/12/11/waiting-for-9-1-knngist/</a> <br>

</div>It is worth noting that the "geometry" native to postgres is very useful for<br>
building tricky multidimensional indices and getting distances in a sort of<br>
"state space" analysis.<br>
<br>
For actual mapping of stuff on the ground, Postgis is way more appropriate.<br>
