If you had a locally installed copy of the required DTDs, it should've
worked, but otherwise I don't see how ... oh, wait. Were you building
from a source tarball? If so, the difference is that up to v16 we
included prebuilt HTML docs in the tarballs, but as of v17 we don't.
So "make world" now triggers a local docs build where before it
didn't.
You can restore things to the status quo ante if you also download
the now-separate docs tarball, eg
https://ftp.postgresql.org/pub/source/v17.0/postgresql-17.0-docs.tar.gz
and unpack that into the same place as the main source tarball.
