I have a PL/pgSQL function that takes two arguments, the first of which
may be null. When the first argument is NULL, the second is set to NULL,
even though a valid value is passed. Is this a documented feature, or
did I miss something?

I can't use overloading, and the order of arguments is important - it is
a site-wide policy.
