AFAIU it is not necessary to stop the server when updating binaries if
one is not going to create extensions, PLs or anything else that will
be dynamically linked after the binaries update and before the server
restart.
So with the process
1. update binaries
2. postgres restart
the downtime will be shorter.
Do I understand something wrong?
