+** <dd> Usually, when a database in wal mode is closed or detached from a 
+** database handle, SQLite checks if this will mean that there are now no 
+** connections at all to the database. If so, it performs a checkpoint 
+** operation before closing the connection. This option may be used to
+** override this behaviour. The first parameter passed to this operation
+** is an integer - non-zero to disable checkpoints-on-close, or zero (the
+** default) to enable them. The second parameter is a pointer to an integer
+** into which is written 0 or 1 to indicate whether checkpoints-on-close
+** have been disabled - 0 if they are not disabled, 1 if they are.
