Follow the procedure below to define a database using client commands.

An example of operations on the server is shown below.

Use psql command to connect to the postgres database.
Execute psql postgres.
```
> psql postgres
psql (<x>) (*1)
Type "help" for help.
```
*1: <x> indicates the PostgreSQL version on which this product is based.
Create the database.
To create the database, execute the CREATE DATABASE databaseName; statement.
```
postgres=# CREATE DATABASE db01;
CREATE DATABASE
```
Confirm that the database is created.
Execute \l+, and confirm that the name of the database created in step 2 is displayed.
```
postgres=# \l+
```
Disconnect from the postgres database.
Execute \q to terminate the psql command.
```
postgres=# \q
```

You can create a database using the createdb command.
