ToxaZ opened a new issue #9373:
URL: https://github.com/apache/airflow/issues/9373
**Apache Airflow version**: 1.10.10
**What happened**:
```python
maintenance_operator = PostgresOperator(
task_id='get_tables_size',
postgres_conn_id='pentaho',
sql='./dags/maintenance/queries/get_tables_size.sql')
```
brings an error
`jinja2.exceptions.TemplateNotFound:
./dags/maintenance/queries/get_tables_size.sql`
**What you expected to happen**:
PostgresOperator not parsing path to file. Instead tries to evaluate path
string as sql query string.
The only way to make it work now:
```python
maintenance_operator = PostgresOperator(
task_id='get_tables_size',
postgres_conn_id='pentaho',
sql=open(
'./dags/pentaho_maintenance/queries/get_tables_size.sql')
.read())
```
**Anything else we need to know**:
Properly worked on airflow 1.10.2
