After updating to Moodle 3.8.2 my daily mysqldump returns an error:
mysqldump: Error 1412: Table definition has changed, please retry transaction when dumping table `mdl_tag_correlation` at row: 0
"retry transaction when dumping table `mdl_tag_correlation` at row: 0" makes no sense to me, what does it mean, or what do I have to do?
The db is set to use utf8mb4_unicode_ci. As well as I remember it initially used a latin character set, which I have changed, but not recently.
In phpMyAdmin I can choose 'Change all tables collations', I do not remember if I have done that - or what it means.
