Here's an updated version of this patch that takes care of the issues I
reported previously: no more repalloc() of the requests array; it's now
an slist, which makes the code much more natural IMV. And no more
messing around with doing sprintf to create a separate sprintf pattern
for the per-db stats file; instead have a function to return the name
that uses just the pgstat dir as stored by GUC. I think this can be
further simplified still.
I haven't reviewed the rest yet; please do give this a try to confirm
that the speedups previously reported are still there (i.e. I didn't
completely blew it).
Thanks
