A GUC read and string compare when off, and (untested as yet) I expect 
little more when on.

Thinking about it, a possibly better alternative is to ship it as a 
library as is done with the pl/pgsql debugger, and use (I think) 
shared_preload_libraries to load it when desired. That way there's zero 
cost if disabled, though a somewhat higher cost if enabled.

Hmm. That'll let me put a test version together that'll work with 9.0 as 
well, so that seems like a no-brainer really, it's just a better way to 
do it. Time for a Pg-on-windows build, yay.
