There's nothing like that built-in, but you could duplicate the
functionality in five minutes with a user-defined function.

plperl or pltcl would probably be the best suited to whacking
strings around, but for a task as simple as this, plpgsql would
do fine too.

I think you'd need to generate a separate function definition for
each number of arguments you wanted to deal with, which is a bit
of a pain in the neck, but it still beats writing an extension
function in C ...
