In the query planner, add a heuristic that will reduce the cost of a full table scan for a materialized view or subquery if the full scan is the outer-most loop. This is shown to speed up some queries. (check-in: e3754cc1 user: drh tags: branch-3.28)

Enhance the b-tree page sorting code to ensure that sqlite3PagerRekey() never overloads a page number and uses only the PENDING_BYTE page for temporary storage. (check-in: 50077428 user: drh tags: trunk)

Do not attempt the OP_Count optimization on queries with HAVING clauses. This fixes a problem exposed by [2cf373b10c9bc4cb]. (check-in: 5f93239a user: drh tags: branch-3.39)

batch-runner.js: add rudimentary metrics export to CSV. Add a toggle to reverse the log output mode (in normal order or most recent first). (check-in: b26e2bc0 user: stephan tags: fiddle-opfs)
16:54
Improved comments in pcache1.c. No changes to code. (check-in: dd017bb1 user: drh tags: trunk)

Any function call can abort. Take this into account when deciding if a DML statement needs a statement journal. See forum thread 9b9e4716c0d7bbd1 for more information. (check-in: 5bf4c5fd user: drh tags: branch-3.39)

batch-runner.js: re-enable unlink-before-run so that OPFS speedtest1 batch can work. (check-in: ba08f7a7 user: stephan tags: fiddle-opfs)
