thanks Ian, Peter and Andres for the replying. One thing I missed to update is that the Source(master) machine I was running is switched off and on everyday. It may have caused any disruption in the WAL files? And one more question, The WAL files are created as 16MB segments, that is obvious. But I do not know when the file is completely written. Is it like, a file is created and then written till 16MB or 16MB data segment is directly written at once. These questions may be stupid but I thought it will help understand the process. ----- -- Thanks, Rajan. -- View this message in context: http://postgresql.nabble.com/WAL-restoration-is-not-happening-completely-tp5930204p5930928.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
