==Introducere==
Acest articol se referă la crearea unei baze de date și a utilizatorului proprietar al acesteia.

==Conectarea la PostgreSQL==
Mergem sub utilizator '''postgres''' user, apoi ne conectăm la PostgreSQL :
<syntaxhighlight lang="bash">
# su - postgres
postgres@vm-postgres:~$ psql
psql (9.1.24lts2)
Saisissez « help » pour l aide.

postgres=#
</syntaxhighlight>

==Crearea bazei de date==
Creăm baza de date '''test''' :
<syntaxhighlight lang="bash">
postgres=# CREATE DATABASE test;
CREATE DATABASE
</syntaxhighlight>

Să verificăm dacă a fost creat:
<syntaxhighlight lang="bash">
postgres=# \l
                                  Liste des bases de données
    Nom    | Propriétaire | Encodage | Collationnement | Type caract. |    Droits d accès
-----------+--------------+----------+-----------------+--------------+-----------------------
 postgres  | postgres     | UTF8     | fr_FR.UTF-8     | fr_FR.UTF-8  |
 template0 | postgres     | UTF8     | fr_FR.UTF-8     | fr_FR.UTF-8  | =c/postgres          +
           |              |          |                 |              | postgres=CTc/postgres
 template1 | postgres     | UTF8     | fr_FR.UTF-8     | fr_FR.UTF-8  | =c/postgres          +
           |              |          |                 |              | postgres=CTc/postgres
 test      | postgres     | UTF8     | fr_FR.UTF-8     | fr_FR.UTF-8  |
(4 lignes)
</syntaxhighlight>

După cum putem vedea, proprietarul bazei de date ''test'' este utilizatorul ''postgres'', vom schimba acest lucru mai târziu.

==Crearea unui utilizator==
Tot conectați la PostgreSQL, creăm un utilizator '''test_user''' cu o parolă '''parola_ikoula''' :
<syntaxhighlight lang="bash">
postgres=# CREATE USER test_user WITH PASSWORD 'password_ikoula';
CREATE ROLE
</syntaxhighlight>

==Schimbarea proprietarului unei baze de date==
În continuare conectați la PostgreSQL, schimbăm proprietarul bazei de date '''test''' baza de date pentru utilizatorul nostru '''test_user''' :
<syntaxhighlight lang="bash">
postgres=# ALTER DATABASE test OWNER TO test_user;
ALTER DATABASE
</syntaxhighlight>

Verificăm dacă proprietarul este modificat pentru '''test_user''' :
<syntaxhighlight lang="bash">
postgres=# \l

           |              |          |                 |              | postgres=CTc/postgres
 template1 | postgres     | UTF8     | fr_FR.UTF-8     | fr_FR.UTF-8  | =c/postgres          +
           |              |          |                 |              | postgres=CTc/postgres
 test      | test_user    | UTF8     | fr_FR.UTF-8     | fr_FR.UTF-8  |
