I have built many billion+ row databases on a laptop with 16 GB RAM, using the 32-bit version. kdb+ uses memory mapping and can support databases much larger than available RAM.

PostgreSQL is a fine choice and I use it for many projects. However, kdb+ is a much better choice when time-series analysis is required.

I'm happy to provide more details if you're interested.
