bdr.bdr_group_join. I was only ever able to get it to work by using
bdr_init_copy and letting it create the database on the target node for me.
Run "SELECT bdr.bdr_node_join_wait_for_ready();" to make sure it
bootstrapped properly.

I can't access my bdr cluster right now, but off the top of my head:
- check the bdr.bdr_connections table in addition to the nodes table.
- make sure you run "select bdr.bdr_connections_changed();" after you
manually delete from any of the bdr tables.
