​CREATE FUNCTION func(arg1 text, arg2​ text) AS $$ SELECT arg1, arg2; $$
LANGUAGE sql; --or something like this

SELECT func(?, ?);

Explanation:

You cannot bind into a DO block because the content of the DO block is text
and Java will not bind to question marks within text. Creating a formal
function and then calling it using a normal SELECT statement with binding
positions - i.e., typical function execution - is thus required.
