NAME¶

ALTER_AGGREGATE - change the definition of an aggregate function

SYNOPSIS¶

ALTER AGGREGATE name ( argtype [ , ... ] ) RENAME TO new_name
ALTER AGGREGATE name ( argtype [ , ... ] ) OWNER TO new_owner
ALTER AGGREGATE name ( argtype [ , ... ] ) 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

argtype

new_name

new_owner

new_schema

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.
