Satellite Repositories

With Satellite 5.6, I defined a postgres-9.3 child channel under the RHEL 6 channel. I then added a postgres-93 repository under the postgres=9.3 channel with the URL http://yum.postgresql.org/9.3/redhat/rhel-rhel-6.5-x86_64. How do I make the packages in the repository available to the channel. When I list the channel, it shows no packages. When I try to add packages, it doesn't show any packages to add.
