How about using the existing reserved keyword "in" followed by "." (dot) and then the function parameter name?
This idea is based on the assumption "in." would always be a syntax error everywhere in both SQL and PL/pgSQL,
so if we would introduce such a syntax, no existing code could be affected, except currently invalid code.
I wouldn't mind using "in." to refer to IN/OUT/INOUT parameters and not only IN ones, it's a minor confusion that could be explained in the docs.
Also, "out." wouldn't work, since "out" is not a reserved keyword.
