ALTER AGGREGATE(7)               PostgreSQL 9.2.24 Documentation               ALTER AGGREGATE(7)



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

       argtype
           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.
