Attached is v2 of the patch, that
(a) adds explicit fsync on the parent directory after all the rename()
calls in timeline.c, xlog.c, xlogarchive.c and pgarch.c
(b) adds START/END_CRIT_SECTION around the new fsync_fname calls
(except for those in timeline.c, as the START/END_CRIT_SECTION is
not available there)
The patch is fairly trivial and I've done some rudimentary testing, but
I'm sure I haven't exercised all the modified paths.
regards
Tomas
