I wrote a similar set of functions to simplify a particular piece of UI code. Three functions called 'str2int'; one takes varchar and returns int, one takes int and returns int, and one takes bigint and returns bigint. I can pass anything the UI works with through these, and I have a guarantee that it'll compare as integer. (The varchar one isn't quite the same as casting to int; it swallows errors and returns 0, because that's what we want to achieve.) Function overloading is awesome!
