That's basically a non-starter because of the delay in reporting from
the stats collector process (ie, even if the information was
"completely
accurate" it'd still be stale by the time that your code gets its
hands
on it). I think you'd be talking about a complete redesign of the
stats
subsystem to be able to use it that way.
BTW, there's some effort going into adding monitoring probes such as
dtrace to PostgreSQL. These would likely be ideal for what you're
trying to do.
