c3ef93f9 db: scale point tombstone averages according to file size
9b9c1284 db: add point tombstone compensation

Release note (bug fix): Fix a storage layer bug that could cause deleted
system.jobs rows to remain on-disk indefinitely. The bloated system.jobs
table could make jobs completely unavailable and prevent DDL statements
from executing. This bug can be detected by examining the system.jobs
table size from the DB Console. This change fixes the bug for Pebble
only and the bug still persists on RocksDB.

Re-run succeeded and it seems unlikely to be related to this change. I don't see an issue tracking a related problem though. I'll create one.
