Here is a tidier version that I'd like to commit before beta2, if
there are no objections. I've added this to the PostgreSQL 11 open
items page. Here's a simple way to reach the error with default
settings in unpatched master (given enough memory and disk):
create table foo (i int);
insert into foo select generate_series(1, 128000000);
set work_mem = '2GB';
select count(*) from foo f1 join foo f2 using (i);
