If user omits port # in database connection string, the test still "goes green" - but the install will fail with a particularly terse error message.  It appears that the test is assuming a port of 5432, but the install itself does not.  If user enters an otherwise invalid port #, such as "999", test will appropriately fail.  It only seems to assume a port of 5432 if none is specified.



Repro steps:
1. begin installation of server with the assumption that you'll be using an external postgres db., i.e., a db that is not on this box.
2. Replace the default Database Connection URL ("jdbc:postgresql://127.0.0.1:5432/rhq") with a string akin to "jdbc:postgresql://foobar.example.com/rhq".  Note that you have "forgotten" to replace the port #
3. Click the "Test Connection" button.
4. Noting that the test returns green, Choose to install (and/or overwrite/keep data, if applicable)
5. Submit.

Current results:
* Test goes green
* Install fails with a cryptic message:
 Could not save the settings for some reason.
Error
Could not save the settings for some reason.

Expected results:
* Test should fail - test should use exact data as entered in the fields from install.  
* Error message should be useful.
