I agree, I&#x27;ve found through painful experience that the shiny and new, while incredibly fun, tends to cost more than it&#x27;s worth.<p>With that said, if you&#x27;re going to take the prudent route and use an established database platform, why in the name of all that is holy would you pick MySQL over Postgres?<p>Granted, I am rather biased, but I do have extensive experience using both in anger. Every time I have to use MySQL I walk away with the impression that it was built with the same design mentality that PHP was. The whole point of a transactional RDBMS is to keep your data as consistent and accurate as possible. I cannot in good faith use a database that (silently!) will coerce badly formatted input into what it thinks should be in the column.
