URL: https://github.com/apache/airflow/issues/37654
### Apache Airflow Provider(s)
google
### Versions of Apache Airflow Providers
<= 10.15.0
### Apache Airflow version
2.8.1
### Operating System
Debian GNU/Linux 12
### Deployment
Official Apache Airflow Helm Chart
### Deployment details
_No response_
### What happened
when total characters of dag_id and task_id greater than 24. (64 - 36 - 4)
PostgresToGCSOperator with argument `use_server_side_cursor = True` run into
psycopg2 error
> psycopg2.errors.SyntaxError: unterminated quoted identifier
### What you think should happen instead
possible expectations
- Add a configuration options for the limitation of postgres identifier
length. (default = 64)
- Detect postgres identifier length before execution. Error out as earier as
possible
- Shorten the `_unique_name` generation for the cursor, currently
```
def _unique_name(self):
return f"{self.dag_id}__{self.task_id}__{uuid.uuid4()}" if
self.use_server_side_cursor else None
```
### How to reproduce
```python
from airflow.providers.google.cloud.transfers.gcs_to_bigquery import
GCSToBigQueryOperator
task = PostgresToGCSOperator(
task_id="t" * 25,
use_server_side_cursor=True,
doc_md=f"""postgres identifier overflow""",
)
```
