It seems correct to me as it is. Chapter 4.1.1 talks about this syntax:

 

postgres=# select U&'d\0061t\+000061';

  ?column?

----------

  data

(1 row)

 

 

Whereas chapter 4.1.2.2 talks about this syntax:

 

postgres=# select E'd\u0061t\U00000061';

  ?column?

----------

  data

(1 row)

 

The former indeed uses 6 digits, whereas the latter uses 8 digits.
