If many people are already using this ‘wrong’ behavior. I agree to change the doc. I also think using ‘null’ may be a better choice. Thanks for your comments.

while at it. we can fix the appearance of jsonb null.

since
select jsonb 'Null';
select jsonb 'NULL';
will fail.

so maybe change
<replaceable>Null</replaceable> in <synopsis> section and
<replaceable>NULL</replaceable>
to
<replaceable>null</replaceable>
