Thank you! Appreciate it :)

Good question. Actually it's not possible for a power loss to occur after a change is made to the database but before the record is marked in the WAL. This is because Postgres ensures that all changes are written to the WAL and flushed to disk before they are applied to the database. This write-ahead mechanism guarantees that even if a power outage occurs immediately after a change is applied, the transaction's record is already safely stored in the WAL.
