There might be better solutions, but when I ran into the same problem, the age(xid) function helped at lot.
Slony contains an xxid data type that follows exactly the xid semantics. It comes with a full operator class so that you can even put indexes on xxid type columns. Shouldn't be too hard to define those operators for the builtin xid type instead.
