Michael Paquier 0ba06e0bfb Allow concurrent-safe open() and fopen() in frontend code for Windows ... PostgreSQL uses a custom wrapper for open() and fopen() which is concurrent-safe, allowing multiple processes to open and work on the same file. This has a couple of advantages: - pg_test_fsync does not handle O_DSYNC correctly otherwise, leading to false claims that disks are unsafe. - TAP tests can run into race conditions when a postmaster and pg_ctl open postmaster.pid, fixing some random failures in the buildfam. pg_upgrade is one frontend tool using workarounds to bypass file locking issues with the log files it generates, however the interactions with pg_ctl are proving to be tedious to get rid of, so this is left for later.
