In hopes of moving this effort along, I've posted a draft patch for that part here: https://www.postgresql.org/message-id/1127261.1769649624%40sss.pgh.pa.us We are running out of time to make this happen for v19, so I suggest focusing your effort if you don't want to see AIX support slide for another year. regards, tom lane
