I am realatively new to PostgreSQL. I have two servers in a Master/Slave relationship using WAL as the replication method. I have what I hope to be an easy question. If the Master goes down and before the slave is promoted, there may be a case where a log file may not have been shipped to the slave yet. If the new Master starts to process new transactions, is there a way to have it process the unshipped WAL files if they are copied to it? I do not see that case in the documentation.
