[arch-general] How to upgrade a postgresql database?
Hello,
I'm trying to upgrade a postgresql database, but it doesn't work. I've also found this: https://wiki.archlinux.org/index.php/PostgreSQL#Upgrading_PostgreSQL
This doesn't work for me, because there isn't any folder /opt/pgsql-9.6/bin anymore - all the binaries are in /usr/bin. This implies, there're no two versions of the binaries available, nor any oldir or newdir (for -b / -B parameters).
It seems, I have to downgrade postgresql first, dump the database, and restore it after upgrading again. Is there any easier method available (i.e. some script which could do this automatically)?
Kind regards
Peter
Hi Peter, What version are you upgrading from? Starting at version 10, you don’t need any particular operation to upgrade minor version (10.X -> 10.Y), that’s why the old binaries are "stuck" at 9.6.

Current version is 9.6, updated version is 10.5

Then you probably missed that part in the wiki page: --- a postgresql-old-upgrade package is available that will always run one major version behind the real PostgreSQL package. This can be installed side-by-side with the new version of PostgreSQL. ---
Upgrading your system (after shutting down postgresql) and installing postgresql-old-upgrade should give you /opt/pgsql-9.6/, your current psql version, and /usr/bin/psql, your target version (10.6). From there, following the wiki should permit you to upgrade the data to the target version.

Thank You - now see I just missed the "postgresql-old-upgrade" - one should read the line to its end. ;-)

The old binaries in /opt are in the package postgresql-old-upgrade, as the very wiki page you linked states.

The confusing point here was the hint "Upgrade the packages:" - I just upgraded my system before trying to upgrade the database, so I thought it wouldn't relate to me ...
