dehowef opened a new issue, #1257:
URL: https://github.com/apache/age/issues/1257
**Describe the bug**
A clear and concise description of what the bug is.
**How are you accessing AGE (Command line, driver, etc.)?**
- [e.g. JDBC]
AGE 1.6.0 on PG15
**What is the command that caused the error?**
I will explain it via example:
```pgsql
create_graph('graph1');
create_graph('graph2);
create_vlabel('graph1', 'label_exclusive_to_graph1');
SELECT * FROM cypher('graph2', $$CREATE (a:label_exclusive_to_graph1
{name:'a'}),
$$) AS (a agtype);
```
When you drop the schemas, this will crash your database.
```pgsql
DROP SCHEMA graph2 CASCADE;
psql:age_install.sql:2: ERROR: label (relation) cache corrupted
psql:age_install.sql:2: FATAL: terminating connection because protocol
synchronization was lost
psql:age_install.sql:2: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
psql:age_install.sql:2: error: connection to server was lost
```
**Expected behavior**
No database crash. Label implementation needs to be reconsidered/fixed
