Never used Riak, no idea. BUT it would be awesome if you did it in both
and could post a comparison. It would be neat to see plus/minus lists
for the db's.
Your question is pretty light on details: "Trade some type of asset".
I'd be curious to see your layouts for both systems. Also the query
types you think you'll need. (One spot Riak might have a problem is
eventual consistency. If you only have 1 more foo, and two people post
buy requests, will Riak sell more than one?)
Riak seems to support distribution, replication, fail over, scale out,
etc. In the sense that Riak is using those words, PG doesn't have all
that stuff.
