here:https://github.com/ccavolt/devcontainer-features/tree/main/src/postgres. As you can see I'm using Debian Bookworm
fortesting. If you open up the repo in a Codespace or a devcontainer and run the following command, you should be able
tosee the same errors that I'll post below: 

You might try installing the Debian packages for the documentation tools; the lack of them is the usual reason for
errorsof that sort:

Yeah, that's what it looks like.  I'm a bit confused though because
16.x should have failed the same way: building our docs without local
DTDs has failed for well over a year now [1].  Perhaps you weren't
trying to build the docs before?

To add confusion to the fire, I was successfully building pre-17 versions ("make world") locally on MacOS fine without
havingto install the documentation tools.  It wasn't until 17 that it failed (and installing the doc tools as
recommendedfixed it).

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.

Ah!  That would be it.
