With what many consider the bad news Sun announced regarding MySQL (certain features will be made closed source and available only to paying customers) is the other open source database, PostgreSQL, licking their lips? Probably. This can only help grow their user base. I happen to operate a moderately popular website music hosting website that runs on MySQL 5 using InnoDB and I am now considering looking into PostgreSQL.
Really this news couldn’t come at a better time. A complete rewrite of my web app is coming soon and the database design needed redone, so why not redo it in a completely open source solution. If Sun continues on this path they will alienate the hardcore open source geeks, this one is definitely going to research into the viability of PostgreSQL.
