@hammerhead See the "Anything else" section of #24388, but you should be
able to still map via `parameters` for the `DELETE` DML in a Jinja-templated
SQL using `{{ task.mapped_kwargs.parameters[ti.map_index].<attribute>}}` as a
workaround.
Assuming the desired SQL `DELETE FROM {table_fqn} WHERE {column} =
{value};`, you could try:
```python
sql = """
DELETE FROM {{ task.mapped_kwargs.parameters[ti.map_index].table_fqn }}
WHERE {{ task.mapped_kwargs.parameters[ti.map_index].column }} = {{
task.mapped_kwargs.parameters[ti.map_index].value }};"""
PostgresOperator.partial(
task_id="delete_partitions",
postgres_conn_id="createdb_connection",
sql=sql,
).expand(parameters=[
{"table_fqn": "tbl1", "column": "col1", "value": "val1"},
{"table_fqn": "tbl2", "column": "col2", "value": "val3"},
)
```
Does this help?
