Sounds good; note that the filesystem will also need recovery thus you may want to consider trying to quiesce the
filesystembefore creating the snapshot to avoid filesystem issues.

Hmm… are you running that on the replica? It should fail; unless you’re running it on the primary.
I wouldn’t bother with pg_start_backup() to take a snapshot backup on the replica. When recovering, the database will
firstdo its crash recovery and then apply any WAL files needed to reach your recovery target time.
