   Example for the second solution:
   
   Create person nodes
   ```
   SELECT * FROM ag_catalog.cypher(
       'people',
       $$ CREATE (a:Person {data:{name:'Jane', 'age': 35}}) $$
   ) as (a ag_catalog.agtype);
   
    a 
   ---
   (0 rows)
   
   SELECT * FROM ag_catalog.cypher(
       'people',
       $$ CREATE (a:Person {data:{name:'Will', age: 21}}) $$
   ) as (a ag_catalog.agtype);
   
    a 
   ---
   (0 rows)
   ```
   
   Retrieve all persons with age 21
   ```
   SELECT * FROM ag_catalog.cypher(
       'people',
       $$MATCH(n {data:{age:21}}) RETURN n$$
   ) as (n ag_catalog.agtype);
   
                                                       n                        
                            
   
---------------------------------------------------------------------------------------------------------
    {"id": 844424930131974, "label": "Person", "properties": {"data": {"age": 
21, "name": "Will"}}}::vertex
   (1 row)
   ```
   
   Retrieve all persons with age greater than 25
   ```
   SELECT * FROM cypher(
       'people',
       $$MATCH(n) WHERE n.data.age > 25 RETURN n$$
   ) as (n agtype);
   
                                                       n                        
                            
   
---------------------------------------------------------------------------------------------------------
    {"id": 844424930131973, "label": "Person", "properties": {"data": {"age": 
35, "name": "Jane"}}}::vertex
   (1 row)
   ```
