I agree entirely.

And there is....

You can log the errors and associated statements, plus lots of other
goodies if you want to a table using a trigger and the system events
that are (I think) new in 9. It also has the advantage that you can
change what events you monitor, or enable/disable monitoring without
bouncing the database.

I have an example set of scripts on my site (utility for trapping
arbitrary server errors or some such wording) . Naturally since I
wrote the script we haven't had a single 1652 (which we were looking
for) but you'll get the idea.
