The case that I can recall most clearly was actually in the other
direction: during system bootup, some NFS volume that was being abused
this way (mount point == data dir) was slow to mount. Compounding the
problem, postgres was being started through some init script that would
helpfully run initdb if it saw the specified data directory was empty.
So, rather than failing like a properly paranoid DBA would wish, it
ran initdb and then started the postmaster.
Ouch.
I wonder though why that directory was writable by the postgres user.
But maybe the helpful start script chown'ed it to fix the "wrong"
permissions.
FWIW, if you want to read the whole gory details of that incident, here
it is:
