I also was working on a project that wanted to use libpq as a subproject
and came up with this independent but similar patch. I chose to develop
it against master.

I think that if we aim to support this workflow that we should add
a test in the tree somewhere. I am happy to develop one if someone
can direct me to a place where they would like it to live. In theory,
the test could even live as a meson test() in the source tree.
