I was a bit curious what the result would be. A quick inspection of the 
query results below gave the impression that the matrix would probably 
show a diagonal line. Even though the table is not necessary as a 
reference to strange equality rules, a table of equality showing a 
diagonal will be easy to remember.

drop table testjsonb;
create table testjsonb(a jsonb);
insert into testjsonb (a) values ('true');
insert into testjsonb (a) values ('false');
insert into testjsonb (a) values ('1');
insert into testjsonb (a) values ('0');
insert into testjsonb (a) values ('-1');
insert into testjsonb (a) values ('"true"');
insert into testjsonb (a) values ('"false"');
insert into testjsonb (a) values ('"1"');
insert into testjsonb (a) values ('"0"');
insert into testjsonb (a) values ('""');
insert into testjsonb (a) values ('null');
insert into testjsonb (a) values ('undefined');
insert into testjsonb (a) values ('Infinity');
insert into testjsonb (a) values ('-Infinity');
insert into testjsonb (a) values ('[]');
insert into testjsonb (a) values ('{}');
insert into testjsonb (a) values ('[{}]');
insert into testjsonb (a) values ('[0]');
insert into testjsonb (a) values ('[1]');
insert into testjsonb (a) values ('NaN');

select  a.a, b.a, a.a = b.a
from    testjsonb a, testjsonb b
