CREATE DATABASE

Creates a new database.

You can't run CREATE DATABASE within a transaction block (BEGIN ... END). For more information about transactions, see Serializable Isolation.

Syntax

CREATE DATABASE database_name [ WITH ]
[ OWNER [=] db_owner ]
[ CONNECTION LIMIT { limit | UNLIMITED } ]

Parameters

database_name

Name of the new database. For more information about valid names, see Names and Identifiers.

WITH

Optional keyword.

OWNER

Specifies a database owner.

=

Optional character.

db_owner

Username for the database owner.

CONNECTION LIMIT { limit | UNLIMITED }

The maximum number of database connections users are permitted to have open concurrently. The limit isn't enforced for super users. Use the UNLIMITED keyword to permit the maximum number of concurrent connections. A limit on the number of connections for each user might also apply. For more information, see CREATE USER. The default is UNLIMITED. To view current connections, query the STV_SESSIONS system view.

Note

If both user and database connection limits apply, an unused connection slot must be available that is within both limits when a user attempts to connect.

CREATE DATABASE Limits

Amazon Redshift enforces these limits for databases.

• Maximum of 60 user-defined databases per cluster.

• Maximum of 127 bytes for a database name.

• Cannot be a reserved word.

Examples

The following example creates a database named TICKIT and gives ownership to the user DWUSER:

create database tickit
with owner dwuser;

Query the PG_DATABASE_INFO catalog table to view details about databases.

select datname, datdba, datconnlimit 
from pg_database_info
where datdba > 1;

 datname     | datdba | datconnlimit
-------------+--------+-------------
 admin       |    100 | UNLIMITED   
 reports     |    100 | 100         
 tickit      |    100 | 100
