A patch that adds an example of a negative substring usage, seems useful to me.

The sources of the docs are simply in the regular postgres docs:
https://github.com/postgres/postgres/blob/e1724af42c7b0bddad2785f8f7a15c4c123862b2/doc/src/sgml/func.sgml#L2786-L2796

Also meson+ninja is these days faster and easier to use than the
configure script:

https://www.postgresql.org/docs/current/install-meson.html

After setting up the build directory with meson you can build the docs using
ninja -C build docs
