How to reset / clear / delete neo4j database?

Question

We can delete all nodes and relationships by following query.

MATCH (n) OPTIONAL MATCH (n)-[r]-() DELETE n,r

But newly created node get internal id as ({last node internal id} + 1) . It doesn't reset to zero.

How can we reset neo4j database such as newly created node will get id as 0?

From 2.3, we can delete all nodes with relationships,

MATCH (n)
DETACH DELETE n

Shut down your Neo4j server, do a rm -rf data/graph.db and start up the server again. This procedure completely wipes your data, so handle with care.
