Disabling the "postgresql" module before building

[Daniel Farina]

Hello all,

I am trying to build some extensions to Postgres on COPR. One of the things that has made life more complex after EL8 or so is the "module" system. It is obligatory to disable the "postgresql" module to be able to install PGDG packages, e.g. https://people.planetpostgresql.org/devrim/index.php?/archives/100-Installin...

I will need to do something similar to build a package with dependencies on postgresql13-devel, and so on.

Unfortunately, I don't see a good way to affect the build chroot in COPR in this way, to disable the included-with-EL8 postgresql module, making adding the Postgres YUM repo (aka "pgdg repo") not useful.

Is there a solution for this?

Thanks in advance.

You can disable particular MODULE:STREAM in the UI:

log-in => project => Settings => (near particular chroot) Edit button
           => Modules: field => specify `!MODULE:STREAM`.

To add a repository, you can use the "Repos:" field on the very same page.
