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

- 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

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.
