[HACKERS] to-do item for explain analyze of hash aggregates?

[Jeff Janes]

The explain analyze of the hash step of a hash join reports something like
this:

   ->  Hash  (cost=458287.68..458287.68 rows=24995368 width=37) (actual
rows=24995353 loops=1)
         Buckets: 33554432  Batches: 1  Memory Usage: 2019630kB


Should the HashAggregate node also report on Buckets and Memory Usage?  I
would have found that useful several times.  Is there some reason this is
not wanted, or not possible?

Cheers,

Jeff
