Sun made an announcement yesterday about some new features for Solaris and OpenSolaris.

Most people are picking up on the inclusion of the PostgreSQL as an included and supported component of the Solaris operating system. Many see PostgreSQL as an interesting choice because it isn't MySQL, the most common and popular of the two choices.

I think PostgreSQL fits into Solaris for the same reason that OpenSolaris fits into the rest of the OS model - it's the less hyped, but exceedingly mature and capable alternative. Incorporating, and more importantly, supporting PostgreSQL on Solaris gives the OS another strong, open source, component that helps to make Solaris a sensible choice for web serving and as a general database platform.
