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. - Heikki
