Move fsync routines of initdb into src/common/ The intention is to used those in other utilities such as pg_basebackup and pg_receivexlog. From: Michael Paquier <michael.paquier@gmail.com>

pg_basebackup pg_receivexlog: Issue fsync more carefully Several places weren't careful about fsyncing in the way. See 1d4a0ab1 and 606e0f98 for details about required fsyncs. This adds a couple of functions in src/common/ that have an equivalent in the backend: durable_rename(), fsync_parent_path() From: Michael Paquier <michael.paquier@gmail.com>

Rename "pg_xlog" directory to "pg_wal". "xlog" is not a particularly clear abbreviation for "write-ahead log", and it sometimes confuses users into believe that the contents of the "pg_xlog" directory are not critical data, leading to unpleasant consequences. So, rename the directory to "pg_wal". This patch modifies pg_upgrade and pg_basebackup to understand both the old and new directory layouts; the former is necessary given the purpose of the tool, while the latter merely avoids an unnecessary backward-compatibility break. We may wish to consider renaming other programs, switches, and functions which still use the old "xlog" naming to also refer to "wal". However, that's still under discussion, so let's do just this much for now. Discussion: CAB7nPqTeC-8+zux8_-4ZD46V7YPwooeFxgndfsq5Rg8ibLVm1A@mail.gmail.com Michael Paquier
