function. To execute this command the user must be the owner
of the function. The input argument types to the function
must be specified, since several different functions may
exist with the same name and different argument lists.
NOTES

information on creating functions.
EXAMPLES
This command removes the square root function:
DROP FUNCTION sqrt(integer);

syntax forms is similar to PostgreSQL's.
