If we had that, I'd put it as a major feature ;)

It's like four relatively large patches (the last being 8868
insertions(+), 6531 deletions(-)), so it's not necessarily easy to break
it down to a 1-line summary, without loosing meaning. Therefore I'd
suggest something general "Significantly improved performance for
analytics queries", unless we want to break those into multiple ones
("faster hashtable for bitmapscan and aggregation", "faster aggregation
when multiple aggregates are used", "faster expression and filter
evaluation"), but that seems a bit excessive...

That's why I'd pointed to specific slides and the commit hashes... Part
of that work is committed in v10, part is not.
