3.8 Requires MYSQL 5 or higher during db upgrade

i use Amazon RDS for my db so don’t know if its related, but when doing the 3.8 update i got an error whenever the db upgrade happened.

ERROR! 3.8 Requires MYSQL 5 or higher

My db is defiantly on 5.6.12 which is more than high enough, so i assume it may be a difference in how RDS works to local db installs.

I got round it by looking at the upgrade functions and changing the db version manually, then clearing the scheduled hook in my theme functions file.

Lukily there wasn’t a major schema update for this release.

the front end worked fine during all of this, but every attempt to access the admin area resulted in being directed to the db upgrade page, then when you hit upgrade i got the above error.

i traced it back to the $wpdb->db_version function which does a prey_match for the version.

doing a query on the db shows this as the version: 5.6.12-log

don’t really know whats happened, i got it fixed manually, but maybe there should be a “force update” option where the user can confirm they are running the right version if the internal checks throw a false error.
