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.)
name
The name (optionally schema-qualified) of an existing aggregate function.
type
An input data type on which the aggregate function operates.
To reference a zero-argument aggregate function, write *
in place of the list of input data types.
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.
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;
