I'm unimpressed; it's not at all clear that you'd be measuring quite the
same thing in, say, mysql as in postgres.
Possibly I have a different view of the uses of dtrace than you do, but
most of the events I'd be interested in probing are probably pretty
Postgres-specific. I think distinguishing half a dozen of them on the
assumption that there should be (exact) matches to that probe point in
most databases is misleading and a source of useless extra notation.
