Hi,

I've tried reworking this and attached the updated diff file here. Since I rarely work on this part of the code,
I'm not entirely sure if it's fully correct — but the functionality seems to work fine in testing.Additionally,
I'm not very familiar with Meson either, so I haven't made any changes to the relevant parts here.

```
postgres(at)zxm-VMware-Virtual-Platform:~/code/postgres$ env | grep COPT
COPT=-Werror
postgres(at)zxm-VMware-Virtual-Platform:~/code/postgres$ make -j8 > /dev/null
postgres(at)zxm-VMware-Virtual-Platform:~/code/postgres$
```
