Hello,

Is asynchronous I/O as introduced in PG 18 also available for Windows 
platform and possibly for Solaris, AIX, FreeBSD platforms ?

If not maybe we should also mention in Server Configuration section that 
asynchronous I/O configuration is only available on Linux platforms.

Is there any other feature only available for specific platforms ? I 
have not found a documentation section mentioning such cases (except for 
installations 
https://www.postgresql.org/docs/18/installation-platform-notes.html).
