Note: If you prepend WAL=off to your connection string, it will disable
the write-ahead log. For more information, see
https://github.com/yesodweb/persistent/issues/363.

A convenience helper which creates a new database connection and runs the
given block, handling MonadResource and MonadLogger requirements. Note
that all log messages are discarded.
Since 1.1.4
wrapConnection :: Connection -> LogFunc -> IO SqlBackend Source
Wrap up a raw Connection as a Persistent SQL Connection.
Since 1.1.5
