@hackage hasql-transaction-io0.2.8.0

Perform IO actions during transactions for Hasql. If you need transactions in hasql but do not need to perform IO in the middle of the transaction, use haslq-transaction. This packages differs from hasql-transaction in that it sacrifices invisible retries for the ability to perform arbitrary IO in the middle of a transaction. This is beneficial when your transaction is long-lived (e.g. when using cursors) and you wish to perform IO with requested data. See hasql-streams-core for an example use case.
