No, you aren't. AFAICT there isn't any way to do that, and I missed it
not too long ago.

I'm not sure about the exact syntax, and certainly I expect this to
become less of an issue with plan invalidation on 8.3, but IMHO it would
be good to have something like Python %(f)s string interpolation (or
just plain string interpolation like in other languages).
