PostgreSQL is a powerful, open source object-relational database system that safely store and scale the most complicated data workloads.

Why dark blue?

If you don't like vivid colors and you already have all your favorite Linux shirts in black, then this dark blue one is the perfect choice.

Buy only good quality, long-lasting clothing!

Forget the cheap, printed T-shirts you can use for one conference only. These you can wear for years, because it is real embroidery on a quality shirt, which you can use way longer than a cheap printed one. Better for you and better for our nature.

Money Back Guarantee

If you're not happy with your order, just send it back within 3 months, and we'll organize a replacement or give you your money back. We have a customer service that cares.

100% made with Linux

The embroidery, the website, the customer service, fully made with Linux. Who else does all this with Linux?

From the price of this item we support the US PostgreSQL Association, supporting the development.
