Hmm, that's not great, and I think I know one factor that has confounded my investigation and the conflicting reports I have received from a couple of people: some are using meson, which is defaulting to -O3 by default, and others are using make which gives you -O2 by default, but at -O2, GCC doesn't inline that StartReadBuffer specialisation that is used in the "fast path", and possibly more. Some of that gap is closed by using pg_attribute_inline_always. Clang fails to inline at any level. So I should probably use the "always" macro there because that is the intention. Still processing the rest of your email...
