   I think it is done using the Postgres relational tables. 
   The `ag_graph` and `ag_label` is stored as a relation under `ag_catalog` 
scheme
   
   ```
   demo=# \dt
              List of relations
      Schema   |   Name   | Type  | Owner 
   ------------+----------+-------+-------
    ag_catalog | ag_graph | table | imran
    ag_catalog | ag_label | table | imran
    public     | company  | table | imran
    public     | employee | table | imran
   (4 rows)
   ```
   
   As you can see that my new graph `cypher` is stored as schema. The `id` and 
`properties` data of the nodes is saved in the table name `_ag_label_vertex`.

   So I think it will be like, first we parse the `cypher` function and then 
perform corresponding psql operations defined.
