This version allows you to declare two functions "foo(variadic numeric)"
and "foo(numeric)", and then if you do a "\df foo" the backend crashes. 

Also, you didn't update an error string:

"variadic argument isn't an array" should (in this version) be something
like: "can't find array type for variadic parameter type %s"

I suggest a slightly different wording for the following error messages:

"aggregate function has variadic argument" -> "variadic parameters not
supported for aggregate functions"


"variadic argument isn't last function's argument" -> "variadic
parameter must be the last parameter to the function"

Those are just suggested wordings.
