# ============================================================================
# Deployment - Hindsight external PostgreSQL (ankane/pgvector)
# Peter Parker, Phase C, t_6d47a360
#
# External-Postgres mode (plan pre-authorized fallback; Phase A proved the
# chart's bundled postgresql is not secret-sourceable). The chart is pointed at
# this instance via values.yaml: postgresql.enabled=false + external.host=
# hindsight-postgres.
#
# IMAGE NOTE (deviation from task body): the task named `ankane/pgvector:15`,
# but that tag does NOT exist — the upstream repo publishes only `latest` plus
# `v0.1.3..v0.5.1` (verified against the docker.io registry API). `latest` is
# postgres:17-bookworm + pgvector v0.8.6. We therefore pin `latest` BY DIGEST
# (sha256:956744bd...) so the deploy is reproducible. This was empirically
# validated on fastpass (pgvector 0.5.1 present, `CREATE EXTENSION vector`
# succeeded, role has rlsuper). Flagged for Ryan in the Phase C report.
#
# POSTGRES_PASSWORD comes from the ExternalSecret (hindsight-credentials,
# key `postgres-password`) — the same value the chart interpolates into
# HINDSIGHT_API_DATABASE_URL, so the server login and the API DSN agree.
