`Error: tuple decompression limit exceeded by operation
Error Code: 53400
Details: current limit: 100000, tuples decompressed: 10906860
Hint: Consider increasing timescaledb.max_tuples_decompressed_per_dml_transaction or set to 0 (unlimited).`

To fix this, use

```sql
SET timescaledb.max_tuples_decompressed_per_dml_transaction TO 0;
```
