Guiseppe, thanks for the patch ! Did you run any benchmarks and
comparison with GiST, Q3C ?
I share the never-finished paper with you.
Regards,Giuseppe.
Also, I'd like to see the number of read blocks from disk for various selects. Explain (analyze, buffers)
Guiseppe, we could provide you machine and catalog, which we used in
our benchmarks. It's be nice if you could repeat tests with your
opclass to have numbers to compare. Alexander will review your PR.
