5988572876 If an "INSERT INTO ... SELECT" can use the xfer optimization, pass the OPFLAG_BULKCSR hint to btree cursors used to update indices. This results in a tighter key packing.

8ff2d9561a When preparing an UPDATE statement, avoid generating VDBE code for those foreign key related actions and constraint checks that may be seen to be unnecessary by considering the subset of table columns potentially modified by the UPDATE.

when new partial indices are created.  This new logic is untested except to
verify that it does not interfere with full indices.

1db95106ee Currently, if SQLite cannot find a table or index referred to by a query, it reloads the database schema from disk to see if the table or index has been added since the schema was cached in memory. Extend this behaviour to columns (which may have been added using ALTER TABLE) and fix some obscure cases related to tables and indexes (INDEXED BY, DROP TABLE etc.).
