I have not had that happen in MySQL either, at least, not with innodb. what command would that be?

I do remember getting bad tables with myisam tables a decade ago, sometimes after a bad shutdown.

I believe this was the command in question: https://dev.mysql.com/doc/refman/8.0/en/repair-table.html

My needs are meager (simple CRUD, low volume), but I haven't had that happen in MySQL either, in over 15 years of running it in production.

Not saying it can't happen, but I don't think it's a common occurrence.

WordPress may be uniquely bad.
