ALTER AGGREGATE — change the definition of an aggregate function
ALTER AGGREGATEname(type) RENAME TOnew_nameALTER AGGREGATEname(type) OWNER TOnew_ownerALTER AGGREGATEname(type) SET SCHEMAnew_schema
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.)
nameThe 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_nameThe new name of the aggregate function.
new_ownerThe new owner of the aggregate function.
new_schemaThe new schema for the aggregate function.
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;
