CREATE DATABASE

Description

creates a new database. To create a database, you must be a superuser or have the special CREATEDB privilege.

The creator becomes the owner of the new database by default. Superusers can create databases owned by other users by using the OWNER clause. They can even create databases owned by users with no special privileges. Non-superusers with CREATEDB privilege can only create databases owned by themselves.

By default, the new database will be created by cloning the standard system database template1. A different template can be specified by writing TEMPLATE name. In particular, by writing TEMPLATE template0, you can create a clean database containing only the standard objects predefined by Greenplum Database. This is useful if you wish to avoid copying any installation-local objects that may have been added to .

name

The name of a database to create.

dbowner

The name of the database user who will own the new database, or DEFAULT to use the default owner (the user executing the command).

The name of the template from which to create the new database, or DEFAULT to use the default template (template1).

encoding

Character set encoding to use in the new database. Specify a string constant (such as 'SQL_ASCII'), an integer encoding number, or DEFAULT to use the default encoding. For more information, see .

tablespace

The name of the tablespace that will be associated with the new database, or DEFAULT to use the template database’s tablespace. This tablespace will be the default tablespace used for objects created in this database.

connlimit

The maximum number of concurrent connections posible. The default of -1 means there is no limitation.

Notes

When you copy a database by specifying its name as the template, no other sessions can be connected to the template database while it is being copied. New connections to the template database are locked out until completes.

The CONNECTION LIMIT is not enforced against superusers.

There is no CREATE DATABASE statement in the SQL standard. Databases are equivalent to catalogs, whose creation is implementation-defined.
