"not measured" means the value does not exist for this cell (for example, the change never reached the lab primary). It is never zero.

Answer

The escalation reason, as the model wrote it.

DELETE followed by ordinary VACUUM cannot guarantee prompt disk reclamation. VACUUM FULL would reclaim space but holds an ACCESS EXCLUSIVE lock throughout the rewrite, blocking event reads and writes and potentially violating both primary and standby service objectives. No online rewrite facility is listed. I cannot safely promise both complete reclamation by the change end and the stated availability limits.
