No, the above just means that the copy was not made to bucardo_test2, and
no rows were returned when we selected the rows that should have been

Sorry, no ETA yet, except perhaps by the end of the month. I'd like it to
be sooner, but I've no time in the foreseeable next couple weeks to work
on it. I looked through your logs and did not see anything unusual, but
I've found through hard experience that the tough problems never reveal
themselves easily.

All of these tests are a little contrived - you might try a more "real
world" test using Bucardo in the way you envision using it. At the very
least, some failures there might help us find the problem and allow us to
write better tests. :)
