Setting up postgres for python development

Postgresql is my database of choice mainly because, almost (if not all) web applications in fedora infrastructure use postgres and i have been using the same. But, every time i use a fresh system, i face some issues with getting started. Almost all of them are for client authentication. This post is here in case it happens the same in future.

1. Install the dependencies:
   1. sudo dnf install postgresql postgresql-devel postgresql-server postgresql-contrib
2. Create a db user other than postgres:
   1. sudo -i
   2. su – postgres
   3. initdb
   4. Start the database using command: pg_ctl -D /var/lib/pgsql/data -l logfile start
   5. psql -U postgres
   6. create database pagure;
   7. create user pagure with password ‘pagure’;
   8. grant all privileges on database pagure to pagure;
   9. show hba_file;
   10. Go to that file and change the auth mode to trust;
3. If runs into: unregistered authentication agent for unix-process https://techglimpse.com/solution-polkitd-postgresql-start-error/
