Subject: [PATCH] state/indexer: close row after query (#6664)

Closes: #6661

Note: see another error during the events indexing, guess the raw tx size exceeds the limitation?
```
3:17PM ERR failed to index block txs err="pq: index row size 2768 exceeds btree version 4 maximum 2704 for index \"tx_results_tx_result_key\"" height=5205112 module=txindex
