Okay, put a developer hat on (even if not one) and imagine this scenario. Imagine you found a CRM-lite web app kind of thing, definitely FOSS, that would be perfect for your office, but you want to add about 2 months of customization to it. After two months, you're done. However, then, on the website where you downloaded that software, you hear that some updates are almost ready for the web app.

I strongly believe that the latest PostgreSQL security patch that I have installed from Ubuntu has slowed down PostgreSQL. It now takes an extra half-second to a second to display a result!

The patch was to block remote SQL injection or something like that, I think.
