Just remember, TANSTAAFL (There ain't no such thing as a free lunch)

in some way, you're paying for a limited or unlimited number of args, be
it money, performance, flexibility.  for postgresql, the payment is that
it gets pretty good performance on <=32 args, without a bunch of ugly code
to handle "unlimited" args.  note that there's still a limit, even in
Oracle, it's likely a performance enforced limit though, i.e. after 1024
args the functions get so slow as to be unusable.
