I checked this in the AIX 7.3 manual and the POSIX 2008 way does not appear to be mentioned there: https://www.ibm.com/docs/en/aix/7.3?topic=r-realpath-subroutine That's a bit confusing, or maybe there are just too many versioning systems to keep track of and I've made a mistake, because it looks like AIX 7.2.5+ has actual certification for Unix V7 AKA SUSv4 AKA POSIX 2008... Or maybe the documentation is wrong and it does actually work. I guess the IBM crew will be forced to look into this as they continue to work on their PostgreSQL/AIX patch, if it doesn't work...
