I'm using Bucardo 4.4.8 to replicate two PG DBs to one central master. My problem is the same as was posted back in 2011 here
The problem is that if one DB in the sync goes offline, bucardo will stop running the sync until the offline DB comes back on. This is a problem because although one node may be offline the other node can still be online and running.
In the above link the responder to the thread claims this was intentionally done by the bucardo developer community because they didn't want to force any action to be taken. I'm curious if anyone else has come across this implementation "problem" and what they've done to mitigate it if anything.
