Hi all,

due to space issue and high volume transaction, some wal segments removed
from pg_xlog on bdr environment.

warning log at node1 saying "requested WAL segment ..... has already been
removed" following Connection reset by peer.

log at node2 :
Sending replication command: START_REPLICATION SLOT
...
...
XX000: data stream ended

I had played streams and goldengate (oracle product) , that at capture side
we can move forward to certain sequence (archivedlog/redolog - wal segment
in postgres).

So, is it possible to move forward to read recent wal segment in bdr
environment? (assume data reconciliation will be done manually).
