Обсуждение: using pg_upgrade on FreeBSD for postgresql installed by ports

Hi all,
is there any best practice in using pg_upgrade to upgrade a cluster
installed using ports on FreeBSD? I mean, the port will install the
binaries over the previous installation therefore removing the old
binaries. May be using the "working" directory before the port get
installed?

Thanks,
Luca

Hello
I recommend you to install the new version in other directory (start the
cluster on other port.... first) and perform the backup with de "NEW"
client.
Restore  the backup(with de "NEW" client), test...and test...and compare.
Then U could promote the new one version to production.

Hope it help

Using the working directory as you wrote might be a good idea (for ephemeral use).
If you want to use the port method, generally you can solve this either by running it inside a jail (pkg -j <jail_id>
installdatabases/postgres93-contrib) , or use the chroot option (pkg -c  
<some_other_path> databases/postgres93-contrib)
However, as much as the use of ports/packages in FreeBSD is advocated over the manual installation, still, PostgreSQL
(andits subprojects) are maybe one of the very few software that you normally  
want to compile them by hand. I avoid the use of packages for postgresql. They don't give you much ease but restrict
yourflexibility. 
So, what you have to do is download the postgresql version you want and compile it, along with its contrib/pg_upgrade
modulein place.  That said, unfortunately, I didn't have much luck in FreeBSD  
trying to upgrade from 9.0 to 9.2 one year ago.
You might give it a try tho. Hmm now that i think about it, i would follow the -c (chroot approach) first (the patches
mighthave solved some problems), and if that proves to be a dependency  
nightmare, then go to the "working directory" solution, then go manual.

Thanks, but this sounds like the "usual" pg_dump/pg_restore chain, I
was wondering about pg_upgrade.
