To reproduce this testdata, run sqlite3 and execute:

	PRAGMA journal_mode = WAL;
	CREATE TABLE t (x);
	INSERT INTO t (x) VALUES (1);
	INSERT INTO t (x) VALUES (2);

And copy & split the WAL into segments:

	sl3 split -o generations/0000000000000000/wal/00000000 db-wal
	cp db-wal 00000000.wal


Then execute:

	PRAGMA wal_checkpoint(TRUNCATE);
	INSERT INTO t (x) VALUES (3);

And split again:

	sl3 split -o generations/0000000000000000/wal/00000001 db-wal
	cp db-wal 00000001.wal


Then execute:

	PRAGMA wal_checkpoint(TRUNCATE);
	INSERT INTO t (x) VALUES (4);
	INSERT INTO t (x) VALUES (5);

And split again:

	sl3 split -o generations/0000000000000000/wal/00000002 db-wal
	cp db-wal 00000002.wal


Finally, remove the original database files:

	rm db*
