> Postgres is software you want to be managed by your distro.
Why?
For production systems I generally try to avoid using anything not built internally. When it comes to PostgreSQL, for example, if you want to submit benchmarks, or you want to report bugs, an important or sometimes a mandatory component is to provide compilation flags. Also, seeing how every kind of storage can act in a different way, tuning of higher-level storage programs seems inevitable. Even though PostgreSQL has a lot of configurations that can be done to the compiled program, some (eg. block size) are compile-time that can only be changed by compiling the program.
