I was going through and patch and trying to understand the idea that what we are trying to achieve here. So basically, generally we start the WAL receiver when we want to fetch the WAL, but if the user has set the parameter WAL_RCV_START_AT_CONSISTENCY then we will start fetching the WAL using walreciver in advance. IMHO the benefit of this idea is that with the GUC we can control whether the extra WAL will be collected at the primary or at the standby node right? One problem is that if the currentsource is XLOG_FROM_ARCHIVE then we might fetch the WAL using both walreceiver as well as from archive right? because we are not changing the currentsource. Is this intentional or do we want to change the currentsource as well? -- Regards, Dilip Kumar EnterpriseDB: http://www.enterprisedb.com
