Options key for a dictionary of SQLite pragma settings with pragma values indexed by pragma names as keys.

All pragma values must be specified as NSString objects. The fullfsync and synchronous pragmas control the tradeoff between write performance (write to disk speed & cache utilization) and durability (data loss/corruption sensitivity to power interruption). For more information on pragma settings, see http://sqlite.org/pragma.html.

Available in Mac OS X v10.5 and later.
