I have been interested in a couchdb api for postgres. But thus far could not find anything.

One option is PouchDB, with levelDOWN* to push it to levelUP* to store it in postgres. But the level of abstraction feels just to much.

I also found another project that basicly keeps a copy in couchdb and sync it over to pg, but stuff like attachments does not work.

* I'm not 100% sure about the projects and how to accomplish it.
