Lockon StratosDB
Target database acquired. Analysing.
Open source... Confirmed, GPLv2.
Supports UNION, INTERSECT, EXCEPT... Confirmed.
Supports full-text search... Confirmed.
Supports XML... Confirmed, SQL extensions, XQuery, XPath.
Supports arrays... Negative Maybe?
Supports user-defined types... Confirmed.
Supports geospatial data... Confirmed-ish.*
Supports graph structures... Confirmed, RDF, SPARQL.
Supports Python... Confirmed, both as client and scripting engine.
Supports HTTP, SMTP, POP, IMAP, NNTP... Confirmed. Wait, what? I thought this was a database.
Openlink Virtuoso could bear further investigation. The Openlink Blog looks satisfyingly full of technical stuffs.
I've also been taking a look at Cubrid, another interesting where-did-that-come-from** open source database.
* You can find a handy feature matrix here. The open source version has all the features of the commercial release, except for clustering, replication, and geospatial data. The lack of replication in the open source version is unfortunate, but in my projects I tend to go for application-level replication anyway.
Funnily enough, I was just looking at the free (as in beer) version of Informix, and that does feature replication and clustering - only two nodes, but what do you want for free?
** Korea, as it turns out.

Looks like another fine example of JWZ's Law: "Every program attempts to expand until it can read mail. Those programs which cannot so expand are replaced by ones which can."

Arrays? Really? Really?

What I want is both arrays and the ability to use said arrays as index components, so I can have:
...
category int[],
posted timestamp,
...
key category (category, posted),
Screw normalisation!

Everybody loves arrays, right up until the day they need to fit a 13th piece of data in their 12-bucket array.
Furthermore, everyone insists "it'll never happen to me," right up until it does.

In Postgres, arrays are unbounded. Well, you can bound them, but it ignores you.

That sounds vaguely obscene, but I guess it works.
