If you are creating databases with similar structures, then one of the most useful additions to the CREATE DATABASE argument is the template. : the name of the database that you want to create, which in my example was “amit”. Once again let’s take a look at the command that was passed at the psql prompt::ĬREATE DATABASE: This is the SQL syntax used to initiate the request for creating the database. If CREATE DATABASE is returned, then it has successfully created the database for you. Similar to creating a user, creating a database is very easy:: postgres=# create database amit There are several other options available, which you can find at the following link. pgpass file while trying to run scripts.) w -no-password: the user will not need to enter a password when connecting. P -pwprompt: this will prompt the user to change the password on their first attempt to log in s -superuser: whether you want to make the user a superuser (a user without restrictions) : the next step is to provide the username that you are trying to create.įollowing the username, you can specify the privileges that you want to grant to the new user.

The reason the command success is returned as CREATE ROLE is that Postgres does not differentiate between a role and a user. In PostgreSQL, a user can easily be created using the CREATE USER command : postgres=# create user amit We will go through the steps for both psql and pgAdmin in order to ensure that you do not get stuck if you are using one or the other. This will help us in eliminating the need for reinstallation, if we mess up the default set of databases or users that already exist, while trying to learn and build our understanding. While working with PostgreSQL the two basic requirements is to create a database and set up a few users. Thus, you can create and configure a new database in a nice UI-based pgAdmin tool.SUMMARY: This article covers the steps for creating new databases and users in PostgreSQL using both psql and pgAdmin: PgAdmin will list a newly created database under the Databases node in the left pane, as shown below.Ĭlick on the database name to expand it, as shown below. Click on Save to create this new database. You can also provide other settings in Defination, Security, Parameters, Advanced, and SQL tabs. Here you can provide a Database name, select owner (postgres will be the owner by default). This will open Create – Database dialog, as shown below.
