Well, the thing is that it's commonly going to be deep down some threads that portability problems cause pain. This is far from the only time. Just a few threads: https://postgr.es/m/CA+TgmoauCAv+p4Z57PqgVgNxsApxKs3Yh9mDLdUDB8fep-s=1...@mail.gmail.com https://postgr.es/m/CA+hUKGK=DOC+hE-62FKfZy=ybt5ulkrg3zczd-jfykm-ipn...@mail.gmail.com https://postgr.es/m/20230124165814.2njc7gnvubn2a...@awork3.anarazel.de https://postgr.es/m/2385119.1696354...@sss.pgh.pa.us https://postgr.es/m/20221005200710.luvw5evhwf6cl...@awork3.anarazel.de https://postgr.es/m/20220820204401.vrf5kejih6jofvqb%40awork3.anarazel.de https://postgr.es/m/E1oWpzF-002EG4-AG%40gemulon.postgresql.org This is far from all. The only platform rivalling AIX on the pain-caused metric is windows. And at least that can be tested via CI (or locally). We've been relying on the gcc buildfarm to be able to maintain AIX at all, and that's not a resource that scales to many users. Greetings, Andres Freund
