ALTER TYPE
Changes the definition of a data type.
Synopsis
ALTER TYPE <name>
OWNER TO <new_owner> | SET SCHEMA <new_schema>
Description
ALTER TYPE changes the definition of an existing type. You can change the owner and the schema of a type.
You must own the type to use ALTER TYPE. To change the schema of a type, you must also have CREATE privilege on the new schema. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have CREATE privilege on the type’s schema. (These restrictions enforce that altering the owner does not do anything that could be done by dropping and recreating the type. However, a superuser can alter ownership of any type.)
Parameters
Examples
To change the owner of the user-defined type email to joe:
ALTER TYPE email OWNER TO joe;
To change the schema of the user-defined type email to customers:
ALTER TYPE email SET SCHEMA customers;
Compatibility
There is no ALTER TYPE statement in the SQL standard.
