I added one for initdb in v8.

Ha, I was just thinking about this, too. I actually split it into 3
patches. The first adds DataDirSyncMethod and uses it for
recovery_init_sync_method. The second adds syncfs() support in
file_utils.c. And the third adds the ability to specify syncfs in the
frontend utilities. WDYT?
