I like this idea. Using a named expression for variadic parameter can
be way. Maybe have to be explicitly enabled. Then we don't need
special keyword or special syntax.
like
CREATE OR REPLACE FUNCTION hstore_constructor(VARIADIC params "anyelement"[])
AS $$ ... $$ STORE_PARAM_NAMES
and maybe we can emulate old behave of hstore.
