MarkMail now has 635,000 PostgreSQL emails loaded and searchable
Comparing PostgreSQL and MySQL is kind of interesting. With all the talk about the LAMP (Linux/Apache/MySQL/PHP-Perl-Python) architecture you’d think MySQL had a lock on the open source database market, but based on simple message traffic analytics, PostgreSQL has a much higher level of community involvement.

“Maria” ，－”a crash-safe alternative to MyISAM”，似乎有作为 InnoDB 继任者的可能。
Yet Another Engine
Apparently Monty and crew have been hard at work on yet another engine for MySQL, this one called “Maria” and is billed as, and I quote, “a crash-safe alternative to MyISAM” (hint, hint, for people still using MyISAM). Apparently it also will support a transactional mode as well, making it a possible successor to InnoDB, and perhaps a competitor to Falcon. It’s not clear how Falcon and Maria will interact in future versions of MySQL (I’d ask on Monty’s blog but it’s one of those unfriendly ones that won’t let the general public post to it).
I’ve still yet to be convinced that the multiple-engine theory is a good one, but it’s good to see that MySQL AB is recognizing the flaws of MyISAM and InnoDB (technical and legal, respectively) and making progress to replace them. Interesting times ahead.

Here’s a list of major features of Maria:
* ACID
* Commit/Rollback
* Concurrent selects (thanks to MVCC)
* Row locking
* Group commit
“Postgres is not for sale”

In light of the recent MySQL sellout, I’d like to once again answer the question that pops up occasionally: “Who will purchase Postgres?” Sure, it brings a smile to those of us immersed in the open source world, but it bears a serious answer: Postgres cannot be bought. While from a distance, MySQL and PostgreSQL look the same (”open-source databases”), they are very different beasts, both in technical and non-technical ways. In a nutshell, the difference can be expressed as:
MySQL is an open-source PRODUCT.
Postgres is an open-source PROJECT.

Couple of random thoughts
* First, better Sun than Oracle. The thought of Oracle eating up MySQL has always been rather disturbing to us especially since we do a fair amount of MySQL consulting and don’t care much for Oracle as a company. I suppose it could still happen.
* Given the fact that Sun is a large contributor to the PostgreSQL project, does this mean PostgreSQL fans can’t make fun of MySQL anymore? Are we like friends now? This could take away some fun and add a little fun at the same time.
* Will this mean MySQL will have no qualms of using PostgreSQL underlying storage engine and what would it be called? - MyPosthttp://www.postgresonline.com/journal/index.php?/archives/23-guid.html
