Your problem isn't with the strings, it's with the smallint parameter.
The undecorated "1" is an integer not a smallint, and it won't be
silently cast in this particular scenario.

I'd suggest declaring the function to take integer. If you really want
the rowtype to use smallint then you can cast internally.
