Postgres synchronizer

Database replication has a lot of overhead. Sometimes I just want to copy a half-dozen rows that change every once in a while. pg_comparator seemed like it would be helpful. It's analogous rsync for Postgres, albeit less efficient. But the version that was out there had a very ambitious version number. I wrote a patch to fix the program, and add the feature of actually performing the update/delete/insert as needed. Hopefully someone finds this useful.
