Postgres easier really? Maybe I should try it again but I'm pretty sure that it's not going to be easier or better or faster this time either. If my application works then I don't switch out the database just for fun, if it doesn't work then a database switch might break it more so the only time I will shop around is when I'm starting a project.
It's easy to understand why MySQL is more popular - MySQL was popular first and easy to setup from the start. The developers were open and responsive. I've been using it since 97 and it's performed well with everything I've done with it. I haven't needed transactions.
Postgres has however always been more popular on /. and I can only attribute that to US vs Europe. If half the effort Postgres proponents have spent bashing MySQL on /. over the years had gone into improving the Postgres manual then setting up Postgres might be easy too. Have you compared the manuals? The Postgres website is defensive. I don't like Oracle though so I would like it if I preferred Postgres.
