Hi,

Really sorry to bring this up at a very odd time, but, I noticed there
is no bigm_similarity_dist().
If I remember correctly, we'd removed it since we could not add an
ORDERING operator to a gin_bigm_ops.

Just wanted to know if we could still add  bigm_similarity_dist() so
that we could do something like:

SELECT * , bigm_similarity_dist(column, '<string-literal>') as d
FROM table
WHERE column =% '<string-literal>'
ORDER BY d ASC;

In case it's a "yes", attached patch would do just that.
