Summary

Only support PostgreSQLPostgres. Remove MariaDB and MySQL support.

This is a SIGNIFICANT improvement with huge potential gain and some risks to mitigate.

This proposal is only our agreement on a single database; to proceed and remove code and documentation related specifically to MariaDB and MySQL. With this proposal we will make an effort but we are not committing to migration guides, scripts, tests, wizards, and case studies easing database migrations. The community is strongly encouraged to gather real-world data, to share and discuss this proposal with all users, encouraging them to create or sponsor creation of these critically important migration materials.
