Thanks Noah and Team,
We (IBM-AIX team) looked into this issue
https://www.postgresql.org/message-id/20240225194322.a5@rfd.leadboat.com
This is related to the compiler issue. The compilers xlc(13.1) and gcc(8.0) have issues. But we verified that this issue is resolved with the newer compiler versions openXL(xlc17.1) and gcc(12.0) onwards.
We reported this issue to the xlc team and they have noted this issue. A fix might be possible in May for this issue in xlc v16. We would like to understand if the community can start using the latest compilers to build the source.
Also as part of the support, we will help in fixing all the issues related to AIX and continue to support AIX for Postgres. If we need another CI environment we can work to make one available. But for time being can we start reverting the patch that has removed AIX support.
We want to make a note that postgres is used extensively in our IBM product and is being exploited by multiple customers.
Please let us know if there are any specific details you'd like to discuss further.
Regards,
Sriram.
