Here's a patch against recent git, but should apply to 8.4 sources as well. It would be interesting to measure the memory and time needed to analyse the table after applying it, because we will be now using a lot bigger bucket size and I haven't done any performance impact testing on it. I updated the initial comment block in compute_tsvector_stats, but the prose could probably be improved.
Just a small follow up. I tried out the patch (or actually a fresh git checkout) and it now gives very accurate results for both upper and lower end of the MCE-histogram with a lower cutoff that doesn't approach 2.
