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

    Note

    The following description applies both to Postgres-XC and PostgreSQL if not described explicitly.

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

    Note

    The following description applies both to Postgres-XC and PostgreSQL if not described explicitly.

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

    Note

    The following description applies both to Postgres-XC and PostgreSQL if not described explicitly.

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
