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;
