Poll: Python Devs, what db do you primarily use?

Both MySQL and PostgreSQL are great, and both are the go-to choice for Python web projects. The main difference between them is that PostgreSQL's replication capabilities that you get out of the box are slightly inferior than what you can get from MySQL.

Of course, if you are not deployed yet, it is ridiculous not to use SQLite - setup time is basically 0.

I'm starting a business in Regensburg, what kind of car should I get? VW Transporter or Citroën C6?

Sorry to mock you, but usually the best DB depends on what you're going to do with it. More reads or more writes, whether replication, etc. pp.

is there any particular reason why youre asking only python developers? are you interesting in particular python bindings?

You left out SQLite.
