DROP
NAME
DROP FUNCTION - remove a user-defined function
SYNOPSIS
DROP FUNCTION name ( [ type [, ...] ] )
INPUTS
name The name of an existing function.
type The type of the function's parameters.
OUTPUTS
DROP Message returned if the command completes successfully.
NOTICE RemoveFunction: Function "name" ("types") does not exist
This message is given if the function specified does not exist in the
current database.
DESCRIPTION
DROP FUNCTION will remove the definition of an existing 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
Refer to create_function(5) for information on creating functions.
No checks are made to ensure that types, operators, access methods, or
triggers that rely on the function have been removed first.
EXAMPLES
This command removes the square root function:
DROP FUNCTION sqrt(integer);
COMPATIBILITY
A DROP FUNCTION statement is defined in SQL99. One of its syntax forms is:
DROP FUNCTION name (arg, ...) { RESTRICT | CASCADE }
where CASCADE specifies dropping all objects that depend on the function
and RESTRICT refuses to drop the function if dependent objects exist.
