What normally happens when you have low amounts of free diskspace and
attempt to upgrade the system?
On FreeBSD (portupgrade) it rolls back any changes it was attempting. I
don't know other systems to be able to say.
Postgresql may require more diskspace to upgrade than most packages,
but if the tools cannot fail cleanly it is already a problem that needs
to be addressed.
