We released e. g. 9.1.1-1 into Ubuntu 11.10, which had the manpage at
the wrong place. For security updates, both Debian and Ubuntu just
take the new upstream version, not the complete backport (including
packaging changes) from the development release. By now, all
Ubuntu releases have e. g. 9.1.5-0ubuntu11.10 in -security, which is
larger than 9.1.4-2~. So if you upgrade from 9.1.5-0ubuntu11.10 to
9.1.5-2, the file moving and alternatives handling must still happen.
There is no predefined upper bound for this, as people might upgrade
from 11.10 or 12.04 to a newer version up to four years in the future,
and postgresql-9.1 might be at version 9.1.18 by then or so.

Right, so for future Debian backports of 9.1 this will be the same
