ALTER AGGREGATE

    Description

    changes the definition of an aggregate function.

    You must own the aggregate function to use ALTER AGGREGATE. To change the schema of an aggregate function, 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 aggregate function’s schema. (These restrictions enforce that altering the owner does not do anything you could not do by dropping and recreating the aggregate function. However, a superuser can alter ownership of any aggregate function anyway.)

    <name>

    The name (optionally schema-qualified) of an existing aggregate function.

    <type>

    <new_name>

    The new name of the aggregate function.

    <new_owner>

    The new owner of the aggregate function.

    <new_schema>

    Examples

    To rename the aggregate function for type integer to my_average:

    To change the owner of the aggregate function myavg for type to joe:

    To move the aggregate function myavg for type integer into schema :

    There is no ALTER AGGREGATE statement in the SQL standard.
