The "desc" parameter from your function declaration matches the DESC keyword in your query, from the looks of it. Either use the old unnamed function declaration and use $1 and $2 in your function, or rename your parameters to something that won't be in your queries as something else than a parameter reference. That said, I don't see where in your function you intend to use those parameters. Possibly you're trying to create a dynamic query? Pavel answered that part of your question already.
