Any idea of the performance overhead?
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.
