Re: assignment vs SELECT INTO

   andrew=# do $x$ declare r abc; begin for i in 1 .. 10000000 loop
   select 'a','b',i into r.x,r.y,r.z; end loop; end; $x$;
   DO
   Time: 63731.434 ms
   andrew=# do $x$ declare r abc; begin for i in 1 .. 10000000 loop r
   := ('a','b',i); end loop; end; $x$;
   DO
   Time: 18744.151 ms


Is it simply because the SELECT is in effect three assignments, so it takes nearly 3 times as long?
