Yes, that occurred to me as well. Frankly I believe the md5 collision
generation is more of a practical issue for crypto where for my
purposes the potential for two residential street addresses to
generate the same md5 hash value is effectively zero. And the md5
function is a builtin which I would hope is faster than anything I
could write in pgsql. Could be wrong, I have been before.

      choose an index scan if your joining column's datatypes do not
      match
