+h5. Configuring an PostgreSQL Database for Jruby Platform
+If you choose to use PostgreSQL and using Jruby, your +config/database.yml+ will look a little different. Here's the development section:
+ adapter: jdbcpostgresql
+ encoding: unicode
+ database: blog_development
+ username: blog
TIP: You don't have to update the database configurations manually. If you had a look at the options of application generator, you have seen that one of them is named <tt>--database</tt>. It lets you choose an adapter for couple of most used relational databases. You can even run the generator repeatedly: <tt>cd .. && rails new blog --database=mysql</tt>. When you confirm the overwriting of the +config/database.yml+ file, your application will be configured for MySQL instead of SQLite.
