Gary R. you are using a frontend that should keep care of user permissions, then you should create one role (user) on postgres with all permission on a database he must own. so, as user postgres create a role for the frontend (eg. groach), then log into postgres as groach and create a database (eg. mydatabase). pgadmin or phppgadmin are your friends if you're not familiar with terminal interfaces in doing this. next add the relevant line to your pg_hba.conf (first line is for clarity). this will grant connection to database `mydatabase` to user `groach` from all ip addresses, using md5 encryption method. # TYPE DATABASEUSERADDRESS METHOD hostmydatabasegroachall md5
Postgresql setup on Debian system
I just switched from using PHP and Mysql to Python / Django and Postgresql. I am having trouble with the setup of Postgresql permissions. I am locked out of some parts of the system and am unsure when to use postgres login vs user login. Most of the Postgresql instructions are written for non-debian like installations. They have one do a bunch of things that Debian does automatically (I think). I found the Debian README confusing, especially in regards to setting up a special shell that I don't think I need. Most of the instructions seem to have already been done automatically. I'm using Debian Wheezy with a KDE4 desktop. My main problem is security although I am not sure whether there are any tweeks that need to be done manually. Tweeks seem to be the rule for most installations. If I seem vague, it's because I'm confused. I need information on security for the engine vs. the individual databases etc. There are various references to changes needed in config files and as mentioned above, the set up of a special shell for Postgresql. I don't understand the need for the shell and don't believe that a lot of the scripts and config changes are necessary if you are using Debian. Most of the documentation I have found seems to concentrate on Windoz and Mac installations. If someone knows where there is an up to date road map for a debian installation I will be eternally grateful. I'm not trying to become a guru on the system, I just want the damn thing to work.

postgresql setup
I found out a little more just now. Having failed to find the debian packager's installation instructions for postgresql I removed the packages from this system. Later I figured to install everything and take another look. I used the current sid tasksel and checked data base and hit ok. The installation went error free until after postgresql-doc got installed then tasksel failed with an error code of 255. So current version of tasksel is not the way to get this done. I'll check out aptitude and see what if any it can clean up and straighten out then do a command line aptitude command to download and install the rest of what's needed. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

re: postgresql setup
Okay, I figured all of it out. postgresql is uninstallable because postgresql-common requires postgresql79 and that's uninstallable. That sets up a situation almost similar to what I encountered when I tried installing emacs and gnus but at least gnus is already in the current version of emacs. So I cleaned out postgresql and will probably be doing my data base work with mysql until mysql gets broken by updates.

re: postgresql setup
This gets stranger by the second. I managed to get postgresql going as user postgres with postgresql -h 127.0.0.1 cr. Then I was able to run createuser dashielljt successfully and createdb too. So I exited the postgres identity and dropped back to dashielljt and tried psql -h 127.0.0.1 and psql asked if connections were being accepted locally on 127.0.0.1 and would not run. so I go back to postgres and ran psql -s and got psql up. I tried \i basics.sql in the /usr/share/doc/postgresql-doc-8.3 tutorial directory and perfectly useable sql queries came up and ran on a weather table several operations for San Fransisco and Hayward. So I'm pretty sure something needs configuring and then it will run.

re: postgresql setup
It makes no difference if you've done su - postgres before running createuser, the same error message appears. I checked that to make sure.

re: postgresql setup
I installed version 8.3.5 with tasksel. When I ran initdb, it ran in debug mode but ran successfully so far as I can tell. I was then able to run postgres -D /usr/local/postgresql/data and the message that came back said postgres was ready to accept connections. I exited that and the database system shut down.

postgresql setup question
I managed to make the postgresql cluster with initdb but can't do anything with createuser because postgresql by default is trying to use a unix socket at address 5432. I'm running on amd hardware and don't know what needs to be done to either enable this socket or go with another alternative so this socket problem goes away. In earlier notes I had used to set up earlier versions of postgresql which I used to try to set 8.3 up I didn't have this problem so am wondering what additional information I need. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
