The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/15/datatype-character.html Description:
In the paragraph > The characters that can be stored in any of these data types are determined by the database character set, which is selected when the database is > created. Regardless of the specific character set, the character with code zero (sometimes called NUL) cannot be stored. For more information refer to Section 24.3. The final sentence ("For more information refer to Section 24.3") is easily read to refer to more information being available about character code zero (NUL). However, section 24.3 has no mention of NUL, but rather the available database character sets. I'd suggest moving that last sentence to immediately after the first sentence, which ends with "...when the database is created." A really minor point, but it caught me off-guard. Best, -Randall
