@Alpha
    default Set<T> collectIntoSet() {
        return set();
    }
Returns results in a {@link Set}. The implementation of the set can be changed by registering a {@link Collector}:
<p>
<pre>{@code
    jdbi.getConfig(JdbiCollectors.class).registerCollector(Set.class, Collectors.toCollection(LinkedHashSet::new));
}</pre>
or
<pre>{@code
    handle.registerCollector(Set.class, Collectors.toCollection(LinkedHashSet::new));
}</pre>
<br>
If no collector is registered, then this method behaves like {@link #set()}.
