I've not yet posted these different threads, but I've split up the meson tree
into subtrees corresponding to pretty much the above.

The meson tree now mainly merges those subtrees together. It still directly
contains the xml-tools dependency wrapper (to be merged soon) and the CI
changes (either later or never).

I've attached a revised version of the xml-tools dependency wrapper (0001):
Cleanups, minor error handling improvements, and bit of comment polishing. I'd
welcome review. But as it fixes a build-dependency bug / FIXME, I'm planning
to push it relatively soon otherwise.

0002 fixes libpq's .pc file (static dependencies didn't show up anymore) and
AIX compilation. AIX doesn't yet support link_whole (support was merged into
meson yesterday though). On the way it also improves comments and a bit of
generic infrastructure. The price for now is that the static libpq is built
separately from the shared one, not reusing any objects. I felt that the
complexity of reusing the objects isn't worth it for now.

Peter, it'd be great if you could have a look at 0002.

0003 mirrors the setup of libpq to the various ecpg libraries. This is a
prerequisite to adding resource files.

0004 adds the resource files

I think after that we could close the CF entry (and create a bunch of followup
entries, as discussed above). Although it somehow seems frivolous to start a
separate thread for "installcheck equivalent" :)
