As allways ... it depends on what you need to know. The documentation of PG is really good. If you are allready a db guru then you should be happy with it. As you are asking this question in the novice forum you might as well never been working with an dbms at all. Probaply you have some existing application that should store its data with PG as backend where you personally wouldn't need to know much besides of setting things up and making a backup now and then. Maybe you expect something like MS-Access that has a powerfull frontend or maybe you know what a rdbms is but want to learn SQL? What will it be?
At the risk of sounding completely dumb and non-responsive, I strongly suggest reading the postgres documentation which includes a tutorial. I also find SQL Cookbook by Molinaro to an extremely useful reference. The power of postgres is contained in no small part by its strong regular expression features. For that I recommend the "bible" Friedl's Regular Expression book from O'Reilly. The study of regular expressions rewards 10-fold every moment it consumes. 73, John On May 21, 2010, at 5:11 PM, Donn Washburn wrote: > Hey Group; > > I have openSuSE 11.3 M7 version pf 8.4.

Basically the setup of Postgres - password, users and then likely.
I am a Linux compTIA Linux+ certified person and have never needed a
true DB.
So that is where I am looking

This is basically true. I have had UNIX FilePro+ or Profile back in the
1980s.
I did build our business software using FilePro+

Yes likely closer to FilePro but I only use or have Linux. No MS
anything here.
I have setup MySQL and used phpMyAdmin. However, it does offer a
message tell you how to setup a password

This is an example of the problem. I went to http://www.postgresql.org/docs/current/static/ and started looking at everything until /tutorial-createdb.html. Where it states createdb. I get as a (system user)donn@m1l-suse:~> createdb mydb createdb: could not connect to database postgres: FATAL: Ident authentication failed for user "donn" The attached file show postmaster is working. I assume this is a security/ issue with a lack of password.

Evidently you have got an installation that sets up "ident" as the standard login authentication method, which is common in Linux packagings of PG but it's not the factory default. Anyway ident insists (by default, again) that your OS-level user name match the database user name you're trying to log in as. Now since you don't have a database user named "donn", that fails. The only database user you do have, most likely, is postgres. So the first thing you want to do is something like sudo su - postgres createuser donn ^D and now you'll be able to connect as user donn. NB: createuser will ask whether to make donn a superuser, which you probably want if you're just playing around. regards, tom lane
As Tom explained in his post the error results from the way authentication is configured in PG's data directory. I think OpenSuse sets it here /var/lib/pgsql In pg_hba.conf you can define how a client has to authenticate devided in 3 zones coming through local (default) or via network port 5432 either on localhost or on the external interface. You created the database "mydb". In Suse's default setting only the unix user "mydb" or a db-superuser can access this db and there has to be a db-usere "mydb", too. You might install pgAdmin as managing tool. It's a binary application available for Linux and Windows. It should be in the OpenSuse repository. http://www.pgadmin.org/ Then there is a web-application phpPgAdmin if you like that better.

It's mostly not version specific, but it does cover version 8. There is nothing about sub-query factoring and the window functions, so it doesn't cover version 8.4. I would still recommend it, though.
