Recursively fsync() the data directory after a crash.
Robert Haas <rhaas@postgresql.org>
Recursively fsync() the data directory after a crash. Otherwise, if there's another crash, some writes from after the first crash might make it to disk while writes from before the crash fail to make it to disk. This could lead to data corruption. Back-patch to all supported versions. Abhijit Menon-Sen, reviewed by Andres Freund and slightly revised by me.
