A hash of sqlstate values that are retryable. When some error happens,
and the value of sqlstate from the result object has a value on this
hash, the query is reset and reintroduced on the query.

=item max_retries => $n

Maximum number of times a query can be retried. When this limit is
reached, the on_error callback will be called.

Note that queries are not retried after partial success. For instance,
when a result object is returned, but then the server decides to abort
the transaction (this is rare, but can happen from time to time).

=item priority => $n

This option allows to prioritize queries. The pool dispatches first those
with the highest priority value.

The default priority is -inf.

Queries of equal priority are dispatched in FIFO order.
