I regularly build GiST indexes on large databases. In recent times, as the size of the database has ballooned (30 million rows) along with the build time on a column of points in 3- and 8-dimensional space (0-volume cube).
Is anyone working on (or already implemented) a parallel GiST build on Cube? If not, I'd like to try contributing this--any pointers from folks familiar with the backend of Cube? Any input would be great.
