I just ran into an interesting thing with unnest and empty arrays.
create table x (
a int,
b int[]
);
insert into x(a,b) values (1, '{}');
insert into x(a,b) values (1, '{}');
insert into x(a,b) values (1, '{}');

insert into x(a,b) values (1, '{}');
select a, b from x;
select a, unnest(b) from x;
insert into
I have to say, this seems straightforward to me. An array with N elements
gets N rows in the result set. I'm curious what other behavior would be
more reasonable.
