I think the scenario there is using dlopen(), possibly via Qt, possibly
via Java, so it's a very specific scenario, not necessarily indicative
of a general requirement on Android, and apparently not using build-time
linking. It's quite conceivable that this issue would also exist with
Qt on other platforms.
As I mentioned before, Meson has Android support. Some people there
clearly thought about it. So I suggest you try building PostgreSQL for
your Android environment using Meson and see what it produces.(*) If
the output files are the same as the autoconf/make build, then I would
think your scenario is nonstandard. If the output files are different,
then we should check that and consider changes to get them to match.
It's of course possible that Meson is wrong, too, but then we need to
have a broader analysis, because the implicit goal is to keep the two
build systems for PostgreSQL consistent.
(*) - This means specifically that the installation trees produced by
"make install-world-bin" and "meson install" should produce exactly the
same set of files (same names in the same directories, not necessarily
the same contents).
