Question

Postgres fails to start after upgrading from postgres:16 to postgres:18 in Docker

Decision Rationale

The proposal describes a Postgres startup failure after upgrading to Postgres 18 due to a changed data directory mount path in Docker, not covered by existing FAQs. The closest related item is a permissions issue in Module 1, but this exact upgrade-path startup problem and its fix are not currently documented.

Placement Details

  • Section ID: module-1
  • Sort Order: End of section
  • Filename Slug: postgres-18-startup-after-upgrade

⚠️ Warnings

  • Back up your data before removing the old volume.
