b7c2f86b85 All WAL frame overwrites even if there are active savepoints. This is safe 
because a ROLLBACK TO will cause all reverted pages to be rewritten to the
WAL file prior to COMMIT.

c9a9022b21 If it is known that checksums will be recalculated on transaction commit, skip calculating checksums when appending frames to the wal file. When recalculating checksums, recalculate them starting with the first overwritten frame - not the first frame in the transaction.
