I've been over how DBEngines calculates their numbers.  That's a correct
assesment; the ranking is more-or-less correct, the numbers are not.
Partly it's because a lot of the metrics they use focus on retrograde
trends (i.e. what has been popular already for several years) and partly
because of stupid things like not counting "Postgres" or "EnterpriseDB".
 Based on my own numbers, MySQL's popularity index (installed base and
people) is still 2X to 3X ours.

Difference is, PostgreSQL adoption is growing whereas MySQL is not.
MariaDB could change that, though; they're picking up a lot of interest.
