Or, maybe it's less mysterious than that. The failure looks like we have not waited long enough for the just-inserted row to get replicated to node C. That wait is implemented as $lsn = $node_a->lsn('insert'); $node_b->wait_for_catchup('node_c', 'write', $lsn); which looks fishy ... shouldn't wait_for_catchup be told to wait for replay of that LSN, not just write-the-WAL? regards, tom lane
