Well, according to Wikipedia, AIX 7.3 (released in 2021) requires POWER8. AIX 7.2 (released 2015) only requires POWER7, and according to the buildfarm page, this machine is POWER7. So it could possibly be upgraded from 7.1 to 7.2, supposing that it is indeed compatible with that release and that Noah's willing to do it and that there's not an exorbitant fee and so on, but that still leaves you running an OS version that is almost certainly closer to EOL than it is to the original release date. Anything newer would require buying new hardware, or so I guess. Put otherwise, I think the reason we're testing on this AIX rather than anything else is probably that there is exactly 1 person associated with the project who has >0 pieces of hardware that can run AIX, and that person has one, so we're testing on that one. That might be a reason to question whether that particular strain of hardware has a bright future, at least in terms of PostgreSQL support. -- Robert Haas EDB: http://www.enterprisedb.com
