Well, ideally it would be 

```ruby
if ActiveRecord.has_sql_connection?
```

but I didn't find any method there, that's why I created this hacky and hard-coded one. Actually, all ActiveRecord is SQL anyways. I think this method is a left-over from when I planned to make Pose available for non-SQL data stores. The Pose paradigm works for any data store that supports range queries (finding words by wildcard search).
