This is a very hard problem in depth.

You will get totally different warning counts per PostgreSQL version,
compiler production, compiler version, probably also different
architectures, different operating systems.  See

https://speakerdeck.com/petere/static-analysis-test-coverage-and-other-12-plus-letter-words slide 6

for example.

Add in the general randomness and cruftiness of buildfarm machines, it's
a complete crap shoot.

Plus you'd need parsers for the output of all the different compilers.
