I tend to agree with Stephen on this, mainly because the point of
these adminpack functions is to expose filesystem access. If these
functions were more "database-y" and less "filesystem-y", I'd agree
with trying to impose database-like consistency requirements.
We don't have to expose every wart of the filesystem semantics
--- for example, it would be reasonable to make pg_file_sync()
Do The Right Thing when applied to a directory, even if the
particular platform we're on doesn't behave sanely for that.
But having fsync separated from write is a pretty fundamental part
of most filesystems' semantics, so we ought not try to hide that.
