Hi Paul!
This is already under discussion, see
https://www.postgresql.org/message-id/flat/1390.1562258309%40sss.pgh.pa.us
although so far I haven't been able to convince everyone about how
fast we should move to adopt it.
We could use your knowledgeable input about
* how quickly do you think that the "posixrules" file is likely
to disappear in major distros, such as Debian, RHEL, macOS?
* what exactly is the incompatibility with -b slim?
