title: Connect Neo4J on an existing Postgresql database
body: <p>I'm a Neo4j new user and I played around with the webadmin interface of Neo4j to create small databases and simple queries in Cypher. Now I want to use Neo4J to create a graph with my existing database. It's a postgresql database with millions of entries with the same structure (Neo4J is very adapted to represent these data). My question is how to import these data ? What is the easiest way to do that ? I already saw that Cypher recognizes csv files but do I have to create a csv file with my data or is there another way to import them ? Thank you for your help. Sam</p>
