What behavior have you observed? the files in pg_xlog like 000010000000000005, 000010000000000006, 000010000000000007, 000010000000000008, (in short term call these 5,6,7,8). with file 8 being most recent and 5 being 2 months back, with respect to time stamp. after I did some work and then observed log files, now 5 and 6 were showing me latest time stamps. I was confused which is the latest one. I also want to know when new WAL segment files is created, is it 16MB or this will start from 0 bytes and size inceases as soon as db server will manupulate. Please provide me if u can some script to identify which one is latest file so that I can copy this to some other place. One more question. Is there a way to build or configure the database server to replicate pg_xlogs ? -Nasir
