In this article, we would like to show you how to create database in PostgreSQL.

Quick solution:

CREATE DATABASE "database_name";

CREATE DATABASE example

In this example, we will create a new database - diraskDB.

Query:

CREATE DATABASE "diraskDB";

CREATE DATABASE IF NOT EXISTS example

You can optionally add IF NOT EXISTS statement, so if the database already exists you won't get an error.

Query:

CREATE DATABASE IF NOT EXISTS "diraskDB";

Popular error

If you try to create a database that already exists with CREATE DATABASE query you will get an error:

PostgreSQL - SQL Error: Can't create database..
PostgreSQL - SQL Error: Can't create database.

If you try to CREATE DATABASE IF NOT EXIST you will get a warning instead:

PostgreSQL - Note: Can't create database..
PostgreSQL - Note: Can't create database.
