回复: Re: A documents mistaken of PG12.5

Hi Heikki,
Thank you very much.You are right.
I think I'm confusing the two syntax.
I think I need a deeper understanding and operation.

祝工作顺利！

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.
