Dear Peter,

Thanks for sharing your script! It's very helpful for us.

While reading your script, however, I had a question about it.
Line 121-122, you defined subscriptions for 2-nodes cluster:

psql -p $port_N1 -c "create subscription sub12 connection 'port=$port_N2' publication pub2 with ($copy_force);"
psql -p $port_N2 -c "create subscription sub21 connection 'port=$port_N1' publication pub1 with ($copy_force);"

But I was not sure it works well.
N2 already have shared data from N1 when subscription sub21 is created.
Did you assume that the initial copying is not so quick and
data synchronization will be not done when creating sub21?
