kind: Postgres
metadata:
  name: postgres-sample
spec:
  # postgresMode: one of 'standalone', 'readreplicas'
  # by default 'standalone' is 1 one primary only, while 'readreplicas' is 1 primary and 1 replica
  postgresMode: 'standalone'

  # Assign 1Gi for each replica persistent volume
  postgresPvcDataSize: 1Gi

  # Enable autoexpansion
  # IMPORTANT:
  # * Kubernetes cluster and pvc MUST support expansion of volumes
  # * In older cluster versions, pods require restart when autoexpanding if Kubernetes feature gate
  #   'ExpandInUsePersistentVolumes' is false. See: https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates/
  # * Rempve postgresPvcDataSize
  # Autoexpansion: if storage available is less than 20% or 'postgresPvcDataAutoexpansionIncrementGib', adjust PVC storage size according to 'postgresPvcDataAutoexpansionIncrementGib' and 'postgresPvcDataAutoexpansionCapGib':
  ## Enable autoexpansion
  # postgresPvcDataAutoexpansion: true
  ## Every time autoexpansion is required, increment 5 GiB
  # postgresPvcDataAutoexpansionIncrementGib: 5
  ## But no more than 25 GiB
  # postgresPvcDataAutoexpansionCapGib: 25

  # Add extra pgbouncer config
