Are you certain your 3rd node's configuration is correct, with all the
right connection strings?

My first guess would be that it's trying to restore the dump to the second
node, as you would've copied the config and changed one dsn but not the
other.

Please show your configuration for each node.

Also, what BDR version are you using? If you built from git, please show
"git rev-parse --short HEAD" from the extension's git tree. If you built
from packages, the package version is sufficient.

BTW, the version after 0.8.0 will include a lot of sanity checks for
connection configurations, making sure everything points at the right nodes
before it does anything.
