Subscriber-only nodes will no longer attempt to take a lock on the cluster when running DDL. The DDL will be executed locally and not replicated to other nodes.
Reduced the lock strength used by the manager process when deleting old rows from the bdr.queue catalog. The previous use of ShareRowExclusiveLock was excessively strict and could lead to a deadlock scenario when concurrently trying to clean up and resolve prepared transactions that had inserted data.
Fixed deadlock between bdr_init_physical cleaning unwanted node data and concurrent monitoring queries.
Fixed an issue when a new node joining the cluster finishes CATCHUP phase before getting its replication progress against all data nodes. This could have caused a new node to be out of sync with the cluster.
