Exact number of mandatory features required for full Core conformance in SQL:2023

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/18/features.html
Description:

I read the ISO IEC 9075-2 2023 and ISO IEC 9075-11 2023, I found that there
are 163 features listed in Table H.1 of ISO IEC 9075-2 2023 and 15 features
listed in Table H.1 of ISO IEC 9075-11 2023.

So should the number be 178 instead of the 177 ?
