ALTER AGGREGATE

Name

ALTER AGGREGATE -- change the definition of an aggregate function

Synopsis

ALTER AGGREGATE 
name
 ( 
type
 ) RENAME TO 
new_name

ALTER AGGREGATE 
name
 ( 
type
 ) OWNER TO 
new_owner

ALTER AGGREGATE 
name
 ( 
type
 ) SET SCHEMA 
new_schema

Description

ALTER AGGREGATE 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 doesn't do anything you couldn't do by dropping and recreating the aggregate function. However, a superuser can alter ownership of any aggregate function anyway.)

Parameters

name

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

type

The argument data type of the aggregate function, or * if the function accepts any data type.

new_name

The new name of the aggregate function.

new_owner

The new owner of the aggregate function.

new_schema

The new schema for the aggregate function.

Examples

To rename the aggregate function myavg for type integer to my_average:

ALTER AGGREGATE myavg(integer) RENAME TO my_average;

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

ALTER AGGREGATE myavg(integer) OWNER TO joe;

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

ALTER AGGREGATE myavg(integer) SET SCHEMA myschema;

Compatibility

There is no ALTER AGGREGATE statement in the SQL standard.
