033564cca9 Within a backup operation, ensure that a read-transaction is opened on the source database before its page size is read. This ensures the page-size used to write to the backup database is the same as its actual page-size, which is important for ZipVFS databases.

e5a0cfa161 Have "sqldiff --rbu" ignore rows with NULL values in primary key fields. RBU can't handle such rows and the documentation already says sqldiff ignores them. Because the code now uses "=" instead of "IS" to filter on primary key columns, diffs on virtual tables are faster now too.
