As it turned out there is Command_Line_Tools_for_Xcode_16_beta.dmg
package available. It can be downloaded from
https://developer.apple.com/ after logging it. I installed it and also
did:
```
cd /Library/Developer/CommandLineTools/SDKs
sudo mkdir __ignore__
sudo mv MacOSX14.* __ignore__
```
... to make sure Postgres will not find the older version of SDK (it
did until I made this step).
Now I get the following output from `meson --setup ...`:
```
The Meson build system

```
... and get the error reported by Stan. Also I can confirm that the
proposed workaround fixes it. Attached is the result of `git
format-patch` for convenience.
Personally I'm not extremely happy with this workaround though. An
alternative solution would be adding the "pg_" prefix to our type
declarations.
Another question is whether we should fix this while the SDK is in
beta or only after it is released.
Thoughts?
I added the patch to the nearest commitfest so that it wouldn't be lost [1].
