CREATE FUNCTION doesn't presently support that.
If the underlying function is written in C, you can fake it by
issuing multiple CREATE FUNCTION commands with different numbers
of declared parameters, all of which point to the same C function.
Then the C code would have to look at fcinfo->nargs to see how it
had been called.
