Not that I'm saying that's "correct" simply that you choose your own definition of popular. I will grant you that mysql has the most downloads of any open source database. Obviously mysql is a database - but it's really not in the same market as Oracle, DB2, Sybase etc.
IMHO mysql got itself scr"wed for all time when it was acquired by Oracle. How better to control what features get added to a low end competitor. At the same time, you're dissuading development on other open source databases by having something with already good functionality.

Sybase will be releasing to CPAN but they're still finishing off work/testing etc.

Niche is a point in time concept. SAP buying Sybase was a significant coupe for both companies. SAP competes head to head with Oracle in applications yet had been beholden to Oracle for its database. This had lead to all the complications you would expect. SAP is now pouring bucket loads of money into development of Sybase. 3 years ago, I was pessimistic that Sybase was going to become another hard to sell legacy skill on my CV (anyone remember SQLPlus: now there's a legacy database skill...). Now, I'm not so sure. SAP is targeting Sybase as being the number 2 commercial database in the world. They were able to add some credibility to that aim with statistics about the number of sites now migrating from Oracle to Sybase. But who knows.

Thanks for your response too. It's only proprietary in the sense that it is written/maintained by SAP/Sybase. They're also releasing similar module for Python, PDP, and so on. They'll all be free and available in the standard locations like CPAN. RegardsChris
