fix: Neo4j driver incompatible with Apache AGE connection URI

[saeedya]

Problem

The Neo4jDatabase class uses the Neo4j driver which expects bolt:// or neo4j:// URI schemes.
However, Apache AGE runs on PostgreSQL and uses postgres:// URIs, causing a ConfigurationError
when running tests.

Error

neo4j.exceptions.ConfigurationError: URI scheme 'postgres' is not supported.
Supported URI schemes are ['bolt', 'bolt+ssc', 'bolt+s', 'neo4j', 'neo4j+ssc', 'neo4j+s']

Steps to reproduce

1. Set up Apache AGE with postgres://localhost:5432
2. Run pytest tests/unit/

Possible solutions

• Use apache_age_python driver directly instead of Neo4j driver for AGE connections
• Or document the correct URI format for connecting Neo4j driver to AGE

Hi, I'd like to work on this issue.

Before starting, I wanted to confirm the preferred approach:

1. Use apache_age_python driver directly for AGE connections
2. Document the correct URI format

Which direction would you prefer?
