When upgrading from 5.0 -> 5.1 the sort order of some german characters
was modified, which meant indexes had to be rebuilt (they are in sorted
order after all). The mysql_upgrade would suggest a table rebuild
(ALTER TABLE xyz ENGINE=INNODB) or dump/restore for every affected
table. I was a consultant during this time, and I can't tell you how
many tables I had to rebuild. Thousands to say the least. Yuck.

Also having to dump/restore to go from 10.2 to 10.3 tables is a PITA
it's a simple no-go and the answer to "should i use postgre or
mysql/mariadb" is always "stay away from postgre, while it got
better you need to dump your data and import them again still way
too often while our mysql tables where created 2002 and now running
on MariaDB 10 without doing such a bullshit a single time"
Remember how awful it was to migrate all those BDB tables to
InnoDB? Or
even just how frustrating it was when UTF8_GENERAL_CI changed
the umlaut?
when did something change umlauts?
as charsets where introdcued with MySQL 5.0 it was a simple script
just to add the correct charset information that it is *not* UTF8 to
5000 tables with not a single char damaged and since we are located
in austria üöäß are very common
