Add PostgresConfiguration fields pg_ident and pg_hba to cluster.yaml

[nealcm]

Currently the cluster.yaml doesn't have several of the PostgresConfiguration fields exposed, even though they're available in the operator code.

https://cloudnative-pg.io/documentation/current/cloudnative-pg.v1/#postgresql-cnpg-io-v1-PostgresConfiguration

It was added in November, but hasn't been exposed to be overridden in the charts:
https://github.com/cloudnative-pg/cloudnative-pg/pull/3534/files#diff-f9048fd2dc7c8ebfb52c2c4156549537ce2a57009e3ffa2e852d28dda9015ebdR2809

pg_hba and pg_ident are supposed to be exposed here, but the cluster.yaml has to be entirely overridden to use them:

https://github.com/cloudnative-pg/charts/blob/main/charts/cluster/templates/cluster.yaml#L54

Suggest adding templating to look at the values.yaml below the parameters.

  postgresql:
    shared_preload_libraries:
      {{- if eq .Values.type "timescaledb" }}
      - timescaledb
      {{- end }}
    {{- with .Values.cluster.postgresql }}
    parameters:
      {{- toYaml . | nindent 6 }}
    {{- end }}
    {{- with .Values.cluster.pg_ident }}
    pg_ident:
      {{- toYaml . | nindent 6 }}
    {{- end }}
    {{- with .Values.cluster.pg_hba }}
    pg_hba:
      {{- toYaml . | nindent 6 }}
    {{- end }}

The MR was closed as a larger solution will be created #343 (comment)

Is there any ETA on this?

[itay-grudev]

@Stevenpc3 I just merged #321 which adds pg_hba. It's on main but not yet released. I plan to release it along with several other breaking changes.

Would you mind creating a PR that adds pg_ident and shared_preload_libraries?

[Stevenpc3]

yes we can add that. Thanks for the update 😄
