Confirms immich-server at the latest v2.7.5 + holds the DB pin immich v2.7.5 ships (14-vectorchord0.4.3-pgvectors0.2.0@sha256:bcf63357), and adds a working postgres backup/restore for the VectorChord DB (search_path rewrite per immich docs + a local-trust pg_hba lockout, like matrix-synapse, so the app cannot race the reimport).

# Postgres backup/restore hook for the immich `database` service (VectorChord/pgvecto.rs). Restore
|
|
# follows the same pattern as the (green) matrix-synapse recipe — a local-trust `pg_hba` lockout so
|
|
# the app can't reconnect and race the reimport — plus the `search_path` rewrite from immich's docs
|
|
# (https://docs.immich.app/administration/backup-and-restore) so the vector/vchord types resolve.
