MironAtHome opened a new issue, #1984:
URL: https://github.com/apache/age/issues/1984
For all currently maintained branches and postgres / age versions, the
behavior of the request
```
SELECT *
FROM cypher('test_graph', $$
MATCH (v)
WITH label(v) as vlabel
RETURN vlabel
$$) AS t(a agtype);
```
is to return an label only, if label has rows.
If the label is created using
`SELECT create_vlabel('<graph_name>', '<vertice_name>')`
vertex will be present, subsequent calls will produce message
```
ERROR: label "<vertex_name>" already exists
SQL state: 3F000
```
however, check for existence using query above won't work.
How is it affects my program.
I need to be able to issue call to create and subsequently, whether rows
present or not, create an index or set of indexes on the vertex.
Request:
Please chose best variant and create either
1 two function label_exists and label_type, with input parameter label_name
2 two fuctions vertex_exists and edge_exists
Personally I would prefer variant 2.
