I've been using Postgres for years and have never heard of Foreign Data Wrappers. A project I'm working on is using both Postgres (PostGIS in particular) and MongoDB, so this would appear to be of use, but I'm not seeing a lot of performance information anywhere. The documentation just states that "there is considerable room for future performance improvements" [0], which makes me a little hesitant.
