PostgreSQL version: 12.2
Operating system:   Windows 10

Sorry for my English
My PG version: "PostgreSQL 12.2, compiled by Visual C++ build 1914,

Example for bag:  
with d (a,b) as (values (null::varchar(255),1))
select * 
from d d1
full join d d2 using (a,b);

"a"	"b"
null	1
null	1

Why select returns 2 records, Is this correct?
