   If I build a docker image from the main branch and run the following::
   ```
   SELECT *
   FROM ag_catalog.drop_graph('threeds', True);
   
   SELECT *
   FROM ag_catalog.create_graph('threeds');
   
   SELECT *
   FROM ag_catalog.cypher('threeds', $$
       CREATE (:begin {name : 'John'})-[:edge1 {name: '1'}]->(:middle)-[:edge1 
{name: '2'}]->(:end)
   $$) AS (a ag_catalog.agtype);
   
   SELECT *
   FROM ag_catalog.cypher('threeds', $$
       MATCH (n:begin {name: 'John'})
       WHERE n.name = 'John'
       RETURN n
   $$) as (v ag_catalog.agtype);
   ```
   
   Then I'm encountering:
   ```
   ERROR: operator is not unique: ag_catalog.agtype = ag_catalog.agtype
   Hint: Could not choose a best candidate operator. You might need to add 
explicit type casts.
   ```
