[bitnami/postgresql] 0.7.1 version does not exist in bitnami chart repo, but only in deprecated-stable chart repo.

Which chart:
bitnami/postgresql

Is your feature request related to a problem? Please describe.
GitLab has a feature called Auto Deploy, which depends on a Helm chart to deploy user's application.

This feature currently uses stable/postgresql chart. For the newer installations, v8.2.1 is used. For the legacy installations v0.7.1 is used.

Now, as you may already notice, the stable chart repository will be gone by Nov 13, 2020. Hence, In GitLab, we decided to move to the bitnami/postgresql chart as it's new standard after the deprecation/removal. However, v0.7.1 does NOT exist in the bitnami/postgresql chart. Hence, we cannot clearly migrate to bitnami's chart.

Can v0.7.1 chart be released in bitnami/postgresql? I see a couple of old versions are available currently, for example,

shinya@shinya-MS-7A34:~/workspace/auto-deploy-image$ helm search repo bitnami/postgresql -l | grep "\s0."

So I think it makes sense to add more legacy chart. Does it make sense?

Describe the solution you'd like
Add v0.7.1 chart (which is identical to stable/postgresql's v0.7.1) to bitnami/postgresql.

Describe alternatives you've considered
If the above solution cannot be accepted, we'll vendor the stable/postgresql in our repository.

Additional context
Since this is time-sensitive task (we need to make a decision by two/three weeks prior to the removal date), I'd appreciate if you'd respond the above question as soon as possible. Thank you for your help!

Hi, I am sorry but the stable/postgresql version 0.7.1 (1 Jun 2017) was not maintained by Bitnami, see the maintainers section in the Chart.yaml file.

At this date, Bitnami has its own bitnami/postgresql Helm Chart hosted in the bitnami repository but without any relation to the one hosted in stable.

It was in stable/postgresql version 2.0.0 (18 Jan 2019) when the bitnami and stable charts were merged and from this moment the Bitnami team maintains the stable/postgresql chart, see wgiddens/charts@2767f19. So this 2.0.0 version is the minimal one that is going to be the same in the stable and bitnami repository.

We already worked with the GitLab team in the past to use the Bitnami Helm Charts as dependencies for the GitLab one, we are happy to help if needed to migrate to a more recent version that can be found in the Bitnami repository, but as I mention, the stable/postgresql 0.7.1 was a different chart no maintained by us so we can't push it to our registry.

@carrodher Thank you for the detailed explanation. We understand that 0.7.1 cannot be listed in bitnami's repository. We'll vendor the old stable/postgresql chart in our repository.
