TropicalPenguin opened a new issue, #369:
URL: https://github.com/apache/age/issues/369
**Describe the bug**
Usually, the MERGE operation works. But when a merge operation follows a
MATCH clause that includes an edge, the server terminates.
**How are you accessing AGE (Command line, driver, etc.)?**
- Command line
- Golang driver
**What data setup do we need to do?**
```pgsql
...
SELECT create_graph('test');
SELECT * from cypher('test', $$ CREATE (a {x:1})-[:foo]->(b {x:2}),(c {x:3})
$$) as (v0 agtype);
...
```
**What is the necessary configuration info needed?**
- N/A
**What is the command that caused the error?**
```pgsql
SELECT * from cypher('test', $$ MATCH ()-[a:foo]->(), (b {x:2}),(c {x:3})
MERGE (b)-[d:bar]->(c) RETURN d $$) as (v0 agtype);
```
Error:
```
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
```
**Expected behavior**
The relationship should be created if it doesn't exist.
**Environment (please complete the following information):**
- Version: 1.1.0, commit ed44f91cb2607605ec2e225248e9ca46e146c215
**Additional context**
