Databases - Practical PostgreSQL

Step 1: Creating the “postgres” User

Create a UNIX user account to own and manage the PostgreSQL database files. Typically, this user is named postgres , but it can be named anything that you choose. For consistency throughout the book, the user postgres is considered the PostgreSQL root or superuser.

You will need to have root privileges to create the PostgreSQL superuser. On a Linux machine, you can use the command shown in Example 2-5 to add the postgres user.

Example 2-5. Adding the postgres User

su - -c "useradd postgres"


Do not try to use the root user as the PostgreSQL superuser. Doing so presents a large security hole.
