<div dir="ltr">Does anyone know if SP-GiST is still available? I never got a reply about a password (<a href="http://www.cs.purdue.edu/spgist/">www.cs.purdue.edu/spgist/</a>) to access the download. Beyond SP-GiST, does anyone know of an existing way to use a quadtree or k-d tree in Postgres? I'm indexing only 2-d points and looking for something that partitions the space.<br>
<br>Thanks,<br>Mose<br></div>
