Recommended action: New databases: mount a single volume at /var/lib/postgresql. Existing data from <=17: pin the old major tag, or run pg_upgrade (both versions) / dump & restore, then move to the new layout. For <=17 keep mounting /var/lib/postgresql/data (mounting /var/lib/postgresql there does NOT persist).
Option: Use the new mount point (new DB) or pin/upgrade [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. New: volumes: - pgdata:/var/lib/postgresql
2. Existing <=17 data: image: postgres:17 (pin) until you pg_upgrade or dump/restore
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
