2.5 Release: PostgreSQL Support

Version 2.5 was released: it adds support for using the PostgreSQL database as backend, alternatively to MySQL.

MySQL is still fully supported. However, PostgreSQL is recommended now, particularly for large installations with dozens of mirrors and more. PostgreSQL support is an important step to a next-generation mirror selection regime that is in the works. Migration is pretty easy; the mb tool can export data in a format the PostgreSQL can understand.

The 2.5 release also sees major improvements in the mirror scanner. It now produces a much more readable output and error reporting. This makes it easier to see spot problems encountered on mirrors. Database operations done by the scanner are more efficient in this release.

The installation instructions have undergone a rework to be more complete, and reflect the recent changes.
