So after last weeks discussion I'm still running into issues trying to
remove a forwarder  and replace it with another forwarder talking to
the remaining replica.

To keep things simple.

1-2
1-3
2-4

Set 1

Want to remove  the forwarder (2), and since the origin is not moving,
doesn't seem a fail-over or switchover fits the bill here.

I've tried to simply drop the path of 2 and run a simple subscribe set
 ( id=1,  provider=3, receiver=4); but the replica seems to get
confused and without restarting slony on the replica  things don't
seem to ever catch up.

Since I'm not replacing the origin and just a forwarder, are there
steps that I should be doing vs just issuing a subscribe to another
forwarder?, I don't want to unsubscribe, I just want the replica to
get it's updates from forwarder (3) now.

When i drop node 2, here is what I've tried.

SLONIK_COMMANDS="$SLONIK_COMMANDS
        SUBSCRIBE SET ( ID = 1, PROVIDER = 3, RECEIVER = 4, forward = no);
        WAIT FOR EVENT ( ORIGIN = 3, CONFIRMED = 4 ) ; <-- run with and without
        UNSUBSCRIBE SET ( ID = 1, RECEIVER = 2);
       DROP PATH ( SERVER = 2, CLIENT = 4 );
       DROP PATH ( SERVER = 4, CLIENT = 2 );
       DROP PATH ( SERVER = 1, CLIENT = 2 );
       DROP PATH ( SERVER = 2, CLIENT = 1 );

This sometimes works and other times does not, again it seems if I
restart the replica (4) things are happy, but I feel that there is
something I'm doing wrong, or out of order?

Thanks again
