I know this push doesn't work, but I really don't get it. Now the unwrap()
error is gone but I get this error.
```
Running "timestamps.slt"
External error: query failed: DataFusion error: simplify_expressions
caused by
Internal error: Optimizer rule 'simplify_expressions' failed, due to
generate a different schema,
original schema:
DFSchema { fields: [DFField { qualifier: None, field: Field { name:
"date_trunc(Utf8(\"year\"),NULL)", data_type: Timestamp(Nanosecond, None),
nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} } }],
metadata: {} },
new schema:
DFSchema { fields: [DFField { qualifier: None, field: Field { name:
"date_trunc(Utf8(\"year\"),NULL)", data_type: Null, nullable: true, dict_id: 0,
dict_is_ordered: false, metadata: {} } }], metadata: {} }.
This was likely caused by a bug in DataFusion's code and we would welcome
that you file an bug report in our issue tracker
[SQL] SELECT DATE_TRUNC('year', NULL);
at tests/sqllogictests/test_files/timestamps.slt:840
