Neo4j Version Compatibility Notes

Neo4j had significant breaking changes between version 4.x and 5.x regarding schema introspection:

Neo4j 5.x+ (current):

• Use SHOW INDEXES instead of CALL db.indexes()
• Use SHOW CONSTRAINTS instead of CALL db.constraints()
• Use CALL db.schema.visualization() for full schema (works in both versions)

Neo4j 4.x and earlier:

• Use CALL db.indexes()
• Use CALL db.constraints()

Safe queries that work across versions:

• CALL db.schema.visualization() - Full schema visualization
• CALL db.labels() - Get all node labels
• CALL db.relationshipTypes() - Get all relationship types

When querying indexes or constraints, prefer the SHOW commands for Neo4j 5+ environments.
