Hi Team,



Just checking in regarding the AIX support patch shared earlier. As
mentioned, we’ve successfully run the patch across all stable PostgreSQL
releases using the build farm, and all tests—including TAP—have passed. We
also ran the build farm scripts locally for PostgreSQL 17 and 18 on AIX,
and the test results were attached for your reference.


We’d appreciate your review and feedback on the patch. Once we receive your
input, our next steps will be:

1. Address any comments or suggestions you may have.

2. Finalize the patch based on feedback.

3. Proceed with integration into the relevant branches.


Please let us know if you need any additional details or clarification.


Thanks

 Vamshi.
