NAME

6       ALTER AGGREGATE - change the definition of an aggregate function

SYNOPSIS

10       ALTER AGGREGATE name ( type [ , ... ] ) RENAME TO new_name
11       ALTER AGGREGATE name ( type [ , ... ] ) OWNER TO new_owner
12       ALTER AGGREGATE name ( type [ , ... ] ) SET SCHEMA new_schema

DESCRIPTION

16       ALTER AGGREGATE changes the definition of an aggregate function.
17
18       You  must own the aggregate function to use ALTER AGGREGATE.  To change
19       the schema of an aggregate function, you must also have  CREATE  privi‐
20       lege  on the new schema.  To alter the owner, you must also be a direct
21       or indirect member of the new owning role, and that role must have CRE‐
22       ATE  privilege  on the aggregate function's schema. (These restrictions
23       enforce that altering the owner doesn't do anything you couldn't do  by
24       dropping  and  recreating  the aggregate function. However, a superuser
25       can alter ownership of any aggregate function anyway.)
26

PARAMETERS

28       name   The name (optionally schema-qualified) of an existing  aggregate
29              function.
30
31       type   An input data type on which the aggregate function operates.  To
32              reference a zero-argument aggregate function, write *  in  place
33              of the list of input data types.
34
35       new_name
36              The new name of the aggregate function.
37
38       new_owner
39              The new owner of the aggregate function.
40
41       new_schema
42              The new schema for the aggregate function.
43

48
49
50       To change the owner of the aggregate function myavg for type integer to
51       joe:
52
53       ALTER AGGREGATE myavg(integer) OWNER TO joe;
54
55
56       To move the aggregate function  myavg  for  type  integer  into  schema
57       myschema:
58
