I think some sort of digest() function that takes a parameter naming the algorithm would be the way to go. That's not
tosay that the existing named functions could continue to exist -- md5() in core and sha1() in pg_crypto. But it sure
seemsto me like we ought to have just one function for digests (or 2, if we also have hexdigest()).
