ALTER AGGREGATE() SQL Commands 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 privi-
lege 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 CRE-
ATE 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 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.
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.
