[postgis-users] Where does Postgres end and PostGIS begin?

[Paragon Corporation]

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?

Will PostGIS have a release that supports Postgres 9.1 and the new GIST

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.
