*So here is a strange question. I am using PostgreSQL 9.4.0 (Yes, I know 9.4.9 is most recent but it's out of my control) O/S is AWS Debian 3.16.7-2 (2014-11-06) x86_64 GNU/Linux. I list the creation time for a WAL file and it shows: /home/mdavidson/dba$ ls -l --time=ctime /d-log/pg_xlog/000000010000000D000000C9-rw------- 1 postgres postgres 16777216 Sep 29 07:14 /d-log/pg_xlog/000000010000000D000000C9but then I list the access time for a WAL file and it shows: /home/mdavidson/dba$ ls -l --time=atime /d-log/pg_xlog/000000010000000D000000C9-rw------- 1 postgres postgres 16777216 Sep 7 14:33 /d-log/pg_xlog/000000010000000D000000C9How is it possible for the WAL file to be accessed BEFORE it was created?Am I overlooking something simple?*
