Satellite Database Creation Fails With 'psql: command not found'.

Issue

When installing Red Hat Satellite 5.7's database, it fails in the following way.  This example assumes one is using Satellite's managed database installation scenario.  This could happen under the embedded database scenario, too.

[root@server cdrom]# ./install.pl --managed-db
* Starting Red Hat Satellite installer.
* Performing pre-install checks.
* Pre-install checks complete.  Beginning installation.
* RHN Registration.
** Registration: System is already registered with RHN.  Not re-registering.
* Checking for uninstalled prerequisites.
** Checking if yum is available ...
There are some packages from Red Hat Enterprise Linux that are not part
of the @base group that Satellite will require to be installed on this
system. The installer will try resolve the dependencies automatically.
However, you may want to install these prerequisites manually.
Do you want the installer to resolve dependencies [y/N]? y
