pgsphere now could benefit very much from our KNNGiST feature. This is
number one development from my point of view. I and Teodor have no
time to work on pgsphere, sorry. But, there are some astronomers I'm working
with, who can take part in this. Sergey Karpov has done extensive benchmarks
of q3c, rtree and pgsphere and found the latter still has some benefits
in some workload, so we are interesting in development.
Could the PostGIS stuff be abused for stellar coordinates?
There is no principal difference between celestial sphere and earth,
it's a matter of conversion between coordinates.
