Hmm.  I don't know about this one.  Durable is an ACID property that
does not apply to all relation kinds.  For example, take an unlogged
table: its data is not durable but its TOAST pointers would be marked
with a VARTAG_DURABLE.  With that in mind ONDISK still sounds kind of
OK for me to use as a name.
