Uh, surely we've got hundreds of instances of that in the system already?

What it looks like that's doing is something similar to appendPQExpBuffer
versus appendPQExpBufferStr, ie, just skipping the overhead of sprintf
format processing when you don't need it.  The implications for
translatability or not are unobvious, so I'm afraid this would result
in confusion and missed translations.

I'm not necessarily against some idea like this, but how do we
separate "translatability" from "sprintf formatting"?
