Also, I suspect you should do something about Meson, but I don't know
what that would look like.
It seems to work already on Meson:
$ <build>
$ touch src/backend/utils/mb/Unicode/win874_to_utf8.map
$ <build>
building for debug
ninja: Entering directory `build-debug'
[2/2] Linking target src/backend/utils/mb/conversion_procs/utf8_and_win.so
I just tried meson build, it seems to only rebuild the corresponding libs without rebuilding Postgres binaries:
```

Is that expected? I think we need Postgres executables to be rebuilt then we can run tests.
