You are right, there are a few warnings:

```
[1566/1887] Compiling C object contrib/pg_tracing/pg_tracing.so.p/span.c.o
../contrib/pg_tracing/span.c: In function ‘get_span_name’:
../contrib/pg_tracing/span.c:210:1: warning: control reaches end of
non-void function [-Wreturn-type]
210 | }
| ^
../contrib/pg_tracing/span.c: In function ‘get_operation_name’:
../contrib/pg_tracing/span.c:249:1: warning: control reaches end of
non-void function [-Wreturn-type]
249 | }
| ^
```

Here is the patch v2 with a quick fix.

both Linux and MacOS. I didn't investigate the issue though.
