mySQL and PostgreSQL major updates

We have deployed PostgreSQL 17.4 (previous 16.x) which is a new major version. We will also in the upcoming week deploy mySQL 8.4.5 (previous 8.0.x) which is also a new major version. The authentication method mysql_native_password is deprecated and deactivated by default in 8.4, replaced by caching_sha2_password. We will re-activate the method on all instances and change to sha2 for root logins. All other user-logins using native would need to have their passwords updated in other to change method. This has to be done before mySQL 9.x is deployed in a few years.

We don't expect major issues with these updates.
