[Maria-discuss] required mysql_upgrade; MDEV-14637
Hello, I have a questions regarding the warnings showing up at 10.2 and 10.3 releases:
When upgrading from MariaDB 10.2.16 or earlier to MariaDB 10.2.17 or higher, running mysql_upgrade is required due to changes introduced in MDEV-14637.
When upgrading from MariaDB 10.3.8 or earlier to MariaDB 10.3.9 or higher, running mysql_upgrade is required due to changes introduced in MDEV-14637.
--
1) The same applies for upgrading <=10.2.16 to >= 10.3.9, right?
2) Does it mean, it is impossible to use "dump and restore" technique, or it only means I need to run the mysql_upgrade afterwards?
3) The problem is not triggered when upgrading from 5.5, 10.0 and 10.1? 4) The problem is not triggered when upgrading to 10.4 ?

just run "mysql_upgrade" after each update and you are done
our production datadirs date back to 2002, originally on windows then moved to MacOS and in 2008 to Fedora and i did not dump/restore a single time in my whole life, this is not postgresql

Just curiosity: does the above statement mean that you consider postgresql less stable than mariadb/mysql? And why..?

PostgreSQL until relatively recently (8.something) required you to dump and restore all your data for a major version upgrade. For some people this was an argument against using PostgreSQL.

beasue any application which can't read it's data after upgrade to a new version is f**g crap and pretty unusable when using as example distro-packages - when you forgot the dump with the old version your are fucked
additionally that means you have downtimes nobody needs, a dist-upgrade here is a "dnf --releasever=xx distro-sync" for 11 years now followed by a reboot like for any kernel update with no downtimes
again: my "mysql" database dates back to version 3.x, that's what i consider production quality

That explains.
Thank you.

I found a reply in the mailing list archive which haven't reached my inbox:

My question is focused on the clarification in our downstream documentation. So while usually I'd be fine with personal experience, in this case, I'd prefer more in-depth answer covering.
I'm forwarding this mail to devel mailing list.
