It depends on the I/O method - as described in the article, "io_uring" is only available on Linux (and requires building with liburing, as well as io_uring to be enabled in the Kernel), but the default (as of beta1) is actually "worker", which works on any operating system.

The "worker" method uses a dedicated pool of I/O worker processes that run in the background, and whilst not as performant as io_uring in our benchmark, did clearly outperform the "sync" method (which is the same as what Postgres currently has in 17 and older).

Windows now also has IORing (see my comment above)

Yes, but what's your point? It's not that we can take this new Postgres version and just compile it in a Windows machine supporting IORing, can we? It requires some effort and time -many times by volunteers- and given that most Postgres deployments are running under Linux, it's understandable that the developers focus on that platform first.
