I dont see how you could know unless you went to all the "large
installations" and asked.  But since its a good idea, and you "should"
do it that way, and because I'm pessimistic, I'd say only 5% of RDB
users do it that way.

Oh!  Joke:  Why do DB Admins make better lovers?  They use surrogates!

Anyway, I'm not a large install, but I use em.  That's gotta count for
something.

Really, how could you count?  Was there a poll someplace?  Ask for some
data.  Otherwise seems like BS to me.
