CREATE FUNCTION chkpass_in(cstring)

CREATE FUNCTION chkpass_out(chkpass)

CREATE FUNCTION raw(chkpass)

--	The various boolean tests:

CREATE FUNCTION eq(chkpass, text)
	RETURNS bool
	AS 'MODULE_PATHNAME', 'chkpass_eq'
	LANGUAGE 'c';

CREATE FUNCTION ne(chkpass, text)
	RETURNS bool
	AS 'MODULE_PATHNAME', 'chkpass_ne'
	LANGUAGE 'c';

--
--	Now the operators.  Note how some of the parameters to some
--	of the 'create operator' commands are commented out.  This
--	is because they reference as yet undefined operators, and
--	will be implicitly defined when those are, further down.
--

CREATE OPERATOR = (
	leftarg = chkpass,
	rightarg = text,
	commutator = =,
--	negator = <>,
	procedure = eq
);

CREATE OPERATOR <> (
	leftarg = chkpass,
	rightarg = text,
	negator = =,
	procedure = ne
);

COMMENT ON TYPE chkpass IS 'password type with checks';
