Seems like this PgSQL upgrade from 9.6 to 11 was painless. Dump-restore was quick as hell.
Note that this transition wasn't HA at all :-)
@ivan hmm, is there a nice way of doing major-version upgrades with pgsql with minimal downtime?
@webmind Minimal downtime is just to replace it in place and run upgrade. But even minute is unacceptable in some environments.
