Nice theory. Won't work in RPM practice. I can't require the user to do
_anything_. Due to the rules of RPM's, I can't even ask the user to do
anything. All I have been able to do is prevent the upgrade from happening
-- but that has its cost, too, as then older library versions have to be held
back just for PostgreSQL, taking up the hapless user's disk space.
While I _can_ version the binaries as Tom mentioned (and that I had thought
about before), in an OS upgrade environment (where my RPMset lives more than
by command line rpm invocation) I can't force the older set to be kept in a
runnable form. It is very possible that the supporting libc shared libraries
will be removed by the OS upgrade -- the old binaries may not even run when
it is critical that they do run.
In place post-binary-upgrade is the only way this is going to work properly in
the environment I have to live with. That's why dump/restore is such a pain,
as Tom remembers.
If I can get older versions building again on newer systems, that will help
buy some breathing room from my point of view.
