The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/16/limits.html
Description:

Under page "https://www.postgresql.org/docs/current/limits.html";, it is
mentioned:

relation size - 32TB
rows per table - limited by the number of tuples that can fit onto
4,294,967,295 pages


32 TB is 35,184,372,088,832 bytes (32*1024*1024*1024*1024).
When we divide this by 8192, we get 4,294,967,296.

So why limit is mentioned 4,294,967,295 pages, instead of 4,294,967,296
pages ?
