In response to Gunther Mayer <[EMAIL PROTECTED]>:
I've been grappling with this and read all sorts of email threads and blog posts but I still have no good solution to the following problem: I want to upgrade a postgresql installation on FreeBSD 6.3 from 8.2 to 8.3 as we'd like to take advantage of its new features and performance enhancements. Yet none of the ports system offers no clean _and_ quick way of performing such an upgrade as the Makefiles of the respective ports choke as soon as they detect an existing older -server or -client.

Yet all I want to do is in a script which fires automatically at 5am via cron (of course I'll get up to check just in case but I've done this many times before):

   1. Do all backup tasks (build packages for all installed postgresql
      8.2 stuff for possible rollback, full database dump, configs etc.)
      and take down all processes that write to the db
   2. Shut down the database
   3. Uninstall all postgresql 8.2 ports (client, server and client libs
      we depend on)
   4. Install all postgresql 8.3 ports
   5. Fire up the new db, restore the complete database dump
   6. Restore the configs (pg_hba.conf, postgresql.conf etc.) and
      restart the database
   7. Start up all "db write" services again

Ideally that process shouldn't take longer than 5 minutes but step number 4 is currently a big stumbling block as

    * Building from ports will take a while
    * I can't find any binary packages for 8.3 (would need i386 for
      testing and amd64 for live) anywhere as far as I can see
      ( has nothing, nor do the mirrors)
    * building binary packages myself is impossible on the same machines
      as pkg_create can only do that with installed packages, "make
      package" et. all choke when they realise you already have
      82-{client,server} installed and I don't see any other way of
      creating a package without installing one

How can I get out of this catch-22 /without /resorting to complicated jail setups or even worse, manual compilations with different prefixes and other nasties? There must be a way to get a package somehow...

Jail setups are not complicated.  You could also make the packages on
another system.  How about doing a make package on the server that you've
tested your application against 8.3 on?  You _have_ done that, right?
That's not an option since my testing box runs i386 while the live one runs amd64, I guess I should really invest in a testing box with the same arch...
What makes you think that jail setups are so complicated.  I set up new
jails almost every week.  I get the impression that you have some reason
for avoiding the obvious solution, and I suspect it revolves around some
incorrect impression that jails are "complicated".
Ok, you're probably right, I just haven't worked with jails before and have just read the wrong articles. I will investigate how I could install the newer version in a jail and keep both running at the same time during the upgrade, I'll probably run into more problems along the way but will post again if I'm stuck.
