That for the article. I had been meaning to look at DB2, and it gave me a
quick summary.

What I get from the article, though, is that DB2 is more modularized than
PostgreSQL, however, it has concurrency issues. Is this true? Anybody allowed
to comment on the peformance of small-sized (~1 million rows) databases?

I'm not seeing a compelling reason to switch.

Cheers,
mark

Unless it's changed recently, it uses shared read locks, so yes, there's
definately concurrency issues to think about.
