NAME
       DROP FUNCTION - remove a function


SYNOPSIS
       DROP FUNCTION name ( [ type [, ...] ] ) [ CASCADE | RESTRICT ]


DESCRIPTION
       DROP  FUNCTION  removes  the  definition  of  an  existing function. To
       execute this command the user must be the owner of  the  function.  The
       argument  types  to  the  function  must  be  specified,  since several
       different functions may exist with the same name and different argument
       lists.


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

       type   The data type of an argument of the function.

       CASCADE
              Automatically drop objects that depend on the function (such  as
              operators or triggers).

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


EXAMPLES
       This command removes the square root function:

       DROP FUNCTION sqrt(integer);


COMPATIBILITY
       A DROP FUNCTION statement is defined in the SQL standard, but it is not
       compatible with this command.
