DROP [AGGREGATE(7)](https://www.chedong.com/phpMan.php/man/AGGREGATE/7/markdown)                  PostgreSQL 14.23 Documentation                  DROP [AGGREGATE(7)](https://www.chedong.com/phpMan.php/man/AGGREGATE/7/markdown)



## NAME
       DROP_AGGREGATE - remove an aggregate function

## SYNOPSIS
       DROP AGGREGATE [ IF EXISTS ] _name_ ( _aggregate_signature_ ) [, ...] [ CASCADE | RESTRICT ]

       where _aggregate_signature_ is:

       * |
       [ _argmode_ ] [ _argname_ ] _argtype_ [ , ... ] |
       [ [ _argmode_ ] [ _argname_ ] _argtype_ [ , ... ] ] ORDER BY [ _argmode_ ] [ _argname_ ] _argtype_ [ , ... ]

## DESCRIPTION
       **DROP** **AGGREGATE** removes an existing aggregate function. To execute this command the current
       user must be the owner of the aggregate function.

## PARAMETERS
       IF EXISTS
           Do not throw an error if the aggregate does not exist. A notice is issued in this case.

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

       _argmode_
           The mode of an argument: IN or VARIADIC. If omitted, the default is IN.

       _argname_
           The name of an argument. Note that **DROP** **AGGREGATE** does not actually pay any attention to
           argument names, since only the argument data types are needed to determine the aggregate
           function's identity.

       _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 argument specifications. To reference
           an ordered-set aggregate function, write ORDER BY between the direct and aggregated
           argument specifications.

       CASCADE
           Automatically drop objects that depend on the aggregate function (such as views using
           it), and in turn all objects that depend on those objects (see Section 5.14).

       RESTRICT
           Refuse to drop the aggregate function if any objects depend on it. This is the default.

## NOTES
       Alternative syntaxes for referencing ordered-set aggregates are described under ALTER
       AGGREGATE (**ALTER**___**[AGGREGATE**(7)](https://www.chedong.com/phpMan.php/man/AGGREGATE/7/markdown)).

## EXAMPLES
       To remove the aggregate function myavg for type integer:

           DROP AGGREGATE myavg(integer);

       To remove the hypothetical-set aggregate function myrank, which takes an arbitrary list of
       ordering columns and a matching list of direct arguments:

           DROP AGGREGATE myrank(VARIADIC "any" ORDER BY VARIADIC "any");

       To remove multiple aggregate functions in one command:

           DROP AGGREGATE myavg(integer), myavg(bigint);

## COMPATIBILITY
       There is no **DROP** **AGGREGATE** statement in the SQL standard.
