That error message was from an earlier release eg 0.4.0
Please check that the following shows a later version.
`select extname, extversion from pg_extension where extname='age';`
extname | extversion
---------+------------
age | 0.5.0
(1 row)
The following was run with version 0.5.0 that shows creating and deleting
nodes
```
CREATE EXTENSION age;
LOAD 'age';
SET search_path = ag_catalog, "$user", public;
SELECT create_graph('my_graph_name');
SELECT * from cypher('my_graph_name', $$
CREATE (a:Part {part_num: '123'}),
(b:Part {part_num: '345'}),
(c:Part {part_num: '456'}),
(d:Part {part_num: '789'})
$$) as (a agtype);
-- Delete a node
SELECT * from cypher('my_graph_name', $$
MATCH (a:Part {part_num: '123'}) DELETE a
$$) as (a agtype);
-- Confirm node deletion
SELECT * from cypher('my_graph_name', $$
MATCH (a)
RETURN a
$$) as (a agtype);
```
