I thing so this is enough - we can get simply message text - like
raise notice statement. I thing so simple and clean function has more
usability than heavy real sprintf function. We (c coders) are old
dinosaurs - but nobody else knows what sprintf function does.

I thing so the name only "format" is good, it's short. If you need
some other formating, just you can use to_char function.
