I once read about an open source database for postal codes with geolocation data but now I can't remember its name. Can someone help?

My guess is that your lost friend is GeoNames.

GeoNames is an excellent site, and Marc is incredibly helpful if you can't quite find what you want. I've just emailed him about some geodata I need and he replied quickly with exactly what I needed.

You can download postal code to name,lat,lng from their site here: http://download.geonames.org/export/zip/

You're looking for an Open GIS database - the main keyword being "GIS". This will help you find results.

The information you're looking for is usually Commercial grade (i.e. you need to pay for the data), but you can see what's available on the open-source GIS websites:

A: 

You can't do it for all countries, because some countries (for example here in the UK), geolocation data are held copyrighted and proprietry with exorbitant licencing fees, which is just ridiculous.

Hopefully at some point in the not too distant future the UK government will see sense and realise the benefit of having open post code data (like the US, which surprised me!)
