17beta1 source download does not include docs & manpages

Hi

16.3 source download includes manpages and html docs.

-bash-5.1$ tar tvf postgresql-16.3.tar | grep html | wc -l
1166
-bash-5.1$ tar tvf postgresql-16.3.tar | grep man1 | wc -l
35


17beta1 does not.

-bash-5.1$ tar tvf postgresql-17beta1.tar | grep html | wc -l
3
-bash-5.1$ tar tvf postgresql-17beta1.tar | grep man1 | wc -l
0

is this intended?

Thanks,
Marcel Hofstetter
