As a developer, Package content allows ORDER_BY in postgres based on EVR comparisons
100%
Description
In order to be able to do things like ORDER BY (EVR) in postgres on the Package content unit, we need to have a type and a comparison method available. Some examples of this include:
Debian:
Spacewalk:
- https://github.com/spacewalkproject/spacewalk/blob/master/schema/spacewalk/postgres/class/evr_t.sql
- https://github.com/spacewalkproject/spacewalk/blob/master/schema/spacewalk/postgres/packages/rpm.pkb#L194
VMaaS:
We should probably adopt one of the existing methods for the Package model.

Is the idea that there will be a field on the model and a DB trigger would populate it?

Depends on the exact approach - VMaaS, for example, creates the evr_t array and inserts it directly:

I see thank you. So we could do it either way.

- Sprint/Milestone set to Priority items (outside of planned milestones/releases)
Priority is high assuming this is blocking support of "keep N versions of RPMs in a repo"
