It specifies the user who will own the database. It determines which locale will be used in the database. It defines the character encoding to be applied in the database. It displays all the commands sent to the server by the createdb command. It is used to specify the tablespace for a new database. It is used to get help regarding createdb arguments from SQL shell. The details given below will illustrate the command line arguments that can be associated with the createdb command: description: it associates an optional comment/description with the newly created database. databasename: it is a user-defined database name. option: it represents a list of command-line arguments that a createdb command can accept. createdb: it is a command that creates a new database in PostgreSQL. Let’s consider the below-listed points for a profound understanding of the createdb command: The basic syntax of the createdb command will go like this: createdb ] The “createdb” command can add some comments/descriptions to the database altogether. However, the “createdb” command can run directly from the command prompt while “CREATE DATABASE” can’t. In PostgreSQL, the “createdb” command is used to generate a new database. The output clarified that the database named “example” has been created successfully. We can verify database creation by executing the “\l”command: The response verifies that the database has been created successfully. Type the below-given command in the psql shell to create a user-defined database named “example”: How does the CREATE DATABASE command work in PostgreSQL? Open the psql shell and execute the “\l” command to see the list of all databases: \lįrom the above-given snippet, we can observe that by default, we have three databases “postgres”, “templete0”, and “template1”. However, to create a database, you should be a superuser, or you should have a special privilege to create a database. Note: To create a PostgreSQL database, we will execute the “CREATE DATABASE” command from the psql(SQL Shell). However, it is preferred to use the uppercase syntax for reserved keywords/commands and lowercase syntax for the user-defined names/attributes. We can write the command in lowercase as well. From the above-given snippet, we can observe that the command is written in uppercase while the database name is written in lowercase. The “CREATE DATABASE” is a predefined command to create a database and the “databasename” is a user-defined database name. Let’s have a look at the below-listed points to understand what we have learned from the above snippet: Here is the basic syntax for creating a database in PostgreSQL: CREATE DATABASE databasename In PostgreSQL, the “CREATE DATABASE” statement is used to generate a new database. How to create a database using CREATE DATABASE? This write-up will explain multiple commands to create a database in PostgreSQL. Once a database is created, then you can perform any specific operation on that database like creating tables, schemas, performing crud operations, and so on. The very first step to get started with any database is to learn how to create a database. PostgreSQL offers a couple of ways to create a new database.
