Development query concerning software collections

Issue

• We have an application delivered as an RPM which is using PostgreSQL 8.4 as a database backend on Red Hat Enterprise Linux 6.6.
• With our current setup, we have specified a dependency from our rpm to postgresql-server >= 8.4.20 and as a result when our rpm is installed, postgresql-server and any required packages are installed.
• We would like to upgrade our application/rpm to use PostgreSQL 9.6 from the RHEL 3.0 software collection.
• Is it OK to add a dependency from an rpm to the PostgreSQL 9.6 software collection (rh-postgresql96 >= 3.0) in the same way as described above?
• The Red Hat documentation on software collections state the following: https://access.redhat.com/documentation/en-us/red_hat_software_collections/3/html/3.0_release_notes/chap-usage#sect-Usage-Deploy

In general, you can use one of the following two approaches to deploy an application that depends on a component from Red Hat Software Collections in production:
•   Install all required Software Collections and packages manually and then deploy your application, or
•   Create a new Software Collection for your application and specify all required Software Collections and other packages as dependencies.

• The documentation specifically states to deploy your application as a software collection and specify all required software collections. However we wish to continue deploying our application as an rpm.
• Is it OK to add a dependency from an rpm to a software collection.
