I'd be pretty happy to have

(a, b) = (x, y);
(a, b) = f(x);

which is SQL-esque.

This is not too far to my proposal - and it is fully adequate alternative. 
 

But what, if anything, does Ada do?

What I know, no, Ada has not this statement - but the design of OUT parameters in Ada absolutely different than PostgreSQL - so in this case we cannot to use Ada language as our base :(
