Description of problem:
if PostgreSQL Database group is selected in anaconda during an install neither
the server or client are actually installed. just support and perl/python libs.
this is counterintuitive to the end user.
automatic inclusion of the server/client when the group is selected, as is the
case in fedora comps.xml, would seem to meet the expectation of the customer better.

Version-Release number of selected component (if applicable):
RHEL3 and RHEL4

How reproducible:
customize installation of RHEL and choose PostgreSQL Database group in anaconda
after installation open a term and try to execute psql.
result will be the command not found.

Steps to Reproduce:
1.install RHEL
2.customize packages during install
3.choose PostgreSQL Database group
  
Actual results:
attempt to execute psql will fail due to the program not being installed

Expected results:
execution of psql

Additional info:
within the comps files for RHEL the server component is optional while in the
fedora comps the server is manditory
the fedora inclusion of the server component is consistent with the expectation
that when a the user selects to install PostgreSQL that the server (and client)
will actually be installed.
Secondarily, installation of the support libraries for perl/python, which is
manditory in RHEL, would seem to be more applicable to selection of the
Development group. But this is less important than the server/client aspect.
i would recommend that the comps file be modified to follow the fedora example
of inclusion of the server as manditory when the group is selected.
