I'm using PostGIS 2.0 with PostgreSQL 9.1 beta 3 (the 2.0), and we had backported these fixes to 1.5.3 so
Both 1.5.3 and 2.0 should work fine with PostgreSQL 9.1 betas. Note they won't work for the alpha releases.

I looked into this more, and I'm guessing the answer is "yes". Looks like PostGIS 1.5.3 can be used with Postgres 9.1 beta. 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?

Nevertheless, it is worth noting that if you are trying to do k nearest neighbor queries, PostgreSQL 9.1 has much better (as in orders of magnitude) indexing support for this particular scenario. See http://www.depesz.com/index.php/2010/12/11/waiting-for-9-1-knngist/ It is worth noting that the "geometry" native to postgres is very useful for building tricky multidimensional indices and getting distances in a sort of "state space" analysis. For actual mapping of stuff on the ground, Postgis is way more appropriate. _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
