Not only is that not a fit storage substrate for Postgres,
it's pretty hard to imagine that it's a fit substrate for
anything. "Every file on this filesystem must belong to the
same owner" is a concept that should have gone out with
floppy disks.
You need some extremely fundamental re-examination of your
design decisions. At the moment I am content to say that
Postgres does not support this storage mechanism and we
do not intend to do so in the future.
