Hello,
Is there a way to know how many pages were hit by a Bitmap Heap scan ?
For instance :
Bitmap Heap Scan on posts
(cost=56.71..295.24 rows=2123 width=67)
(actual time=0.575..1.462 rows=2160 loops=1)
I'd like to know if it hit 2160 pages (ie I should really run CLUSTER) or
50 pages (ie. my table is well clustered, everything cool).
Since, when it's cached, it's so fast anyway I cant' tell the difference,
but when it's not cached, it is important.
This would give an interesting probe for EXPLAIN ANALYZE tuning...
