By extension, would this also mean things like
select row(1,2,3)::foo = foo from foo;
or
select (1,2,3)::foo = (1,2,3)::foo;
or
select (1,2,3) = (1,2,3)::foo;
Would work (presumably as row-wise comparison does)? Also,
create index foo_idx on foo(foo);
select * from foo where (1,2,3)::foo = foo;
would be very nice.
