In the PostgreSQL world it is common not to use passwords for authentification as MySQL does but to 

I tried running ``roundup-admin initialise`` as user ``django`` and leaving the password of my tracker empty (``password = ``). Then I get this exception:

roundup.hyperdb.DatabaseError: FATAL:  password authentication failed for user "django"

Next thing I tried was another syntax in the INI file: ``password = ''``. The exception I get is the following:

raise hyperdb.DatabaseError, message
roundup.hyperdb.DatabaseError: fe_sendauth: no password supplied

So it looks like it got it that I want to use *no* password, but it doesn't let me.

I'm far from a postgres expert but I think this handled on postgres' end of things.

When my pg_hba.conf just had the line:
host    all         all         127.0.0.1/32          md5

Then I got the same exception you mention. If you add:
host    all         roundup     127.0.0.1/32          trust

(where roundup is whatever username you're using for the roundup user) then it should work.

I just tested it on my postgres 8.2/psycopg 2.0.5.1 and it worked.

Closing as "Works for Me" based on my previous comment.

If we get a report with some more details about the postgres side that contradict my admittedly limited knowledge of postgres I'd be happy to look at it in more detail.
