Stephan Vollmer reported low GiST indexing performance with tsearch2.
Tom Lane and Martijn van Oosterhout investigated and after some
discussion on the performance list they identified a bit counting
function as the culprit. Tom committed an alternative implementation
using a static lookup table to various contrib modules (intarray,
ltree, trgm and tsearch2) that resulted in a 20x performance
improvement for large indexes. Discussion about further improving the
so called "picksplit" algorithm for another 10x gain ensued but did
not reach a conclusive resolution, at least not for the 8.1 branch.
