From what I've seen on the list so far upgrades are advised precisely
because somebody has had to ask for help with a problem - one that's
usually resolved in newer versions. Doubly so because the issues raised
are usually performance related or are caused by limitations in 7.3 (or
whatever they're running).
If upgrading solves a problem that somebody is asking for help with,
then advising the user to upgrade makes sense.
Consider operating systems. An OS vendor might expect a given version to
be used for five years or more, but if you ask them for help because
you're encountering awful performance with 2TB disks or high CPU load on
10GigE networks they're quite likely to advise you to upgrade the OS to
a version with enhancements that solve your problems.
That says nothing about the people out there still using 7.3 and similar
without problems, running well within its capabilities and happy with
what it's doing. I doubt many people would advise them to upgrade - at
least not in a hurry and not with any jumping and hand-waving.
I often see responses along the lines of "if you're using 8.3 then just
do <blah> otherwise you'll need to...." - so there doesn't appear to be
any assumption that the first step must be to upgrade to the latest version.
My impression from using PostgreSQL is that people using old versions
are taken seriously. Data corruption, crash and security bug fixes get
applied to very old versions. For example, 7.3.21 was released on Jan
2008, and includes several fixes:
Given that 7.3 was released in late 2002:
I think that's pretty good myself.
Given that PostgreSQL upgrades aren't trivial, it's important to have
these ongoing releases for older versions. It's great to see that need
so well met.
