ALTER DATABASE

The ALTER DATABASE command modifies the definition of a database.

Syntax

ALTER DATABASE database_name 
    alter_option;

alter_option depends on the operation you want to perform on the database. For all supported clauses, see the sections below.

Clause

OWNER TO

ALTER DATABASE database_name
    OWNER TO new_user;

Parameter or clause	Description
OWNER TO	This clause changes the owner of the database. To alter the owner, you must be able to SET ROLE to the new owning role, and you must have the CREATEDB privilege. Note that superusers have all these privileges automatically.
new_user	The new owner you want to assign to the database.

-- Change the owner of the database named "database1" to user "user1"
ALTER DATABASE database1 OWNER TO user1;

RENAME TO

ALTER DATABASE database_name
    RENAME TO new_name;

Parameter or clause	Description
RENAME TO	This clause changes the name of the database. Only the database owner or a superuser can rename a database; non-superuser owners must also have the CREATEDB privilege. The current database cannot be renamed. (Connect to a different database if you need to do that.)
new_name	The new name of the database.

-- Change the name of the database named "database" to "database1"
ALTER DATABASE database RENAME TO database1;
