Added Initial PostgreSQL support

Very good start! I will try to have a look today or tomorrow.

Under docs - some readme files would need some enhancements.
Mainly: https://github.com/linkdotnet/Blog/blob/master/docs/Storage/Readme.md

[EliasMasche]

There I updated the docs listing PostgreSql

[linkdotnet]

Small other things:

• In https://github.com/linkdotnet/Blog/blob/master/docs/Setup/Configuration.md the new provider should be added in the "PersistenceProvider" explanation.

I guess I put it wrongly in: #207 (comment)

The initial changes so that PostgreSql works without any exception, should work. So UpdateDate and ScheduledPublishDate should be in UTC. This should be part of this PR, otherwise it will not work. At least this is my understanding, right?

But other parts like the Background-jobs, I will take over once merged.

Yes, there is a little confusion, I will include the details, and any recommendations or tips on where to apply the UTC config when using PostgreSQL or where to look still taking me time to navigate through the project

Take your time. I am no expert on Postgres.
But in the code there aren’t too many places. Mainly when a new blog post is created or updated.

I was able to update DateTime to UtcNow from BlogPost.cs
var blogPostUpdateDate = scheduledPublishDate ?? updatedDate ?? DateTime.UtcNow;

When you need to publish now, ' ScheduledPublishDatetriggers the exception ofKind=Unspecified` from PostgreSql when you schedule the post's release.

These three steps are handled in the fields CreateNewBlogPost.razor, CreateNewModel.cs, and BlogPost.cs where is gonna the best place or time to adapt the local time to Utc

[linkdotnet]

Good start. I get an exception when I try to set the scheduled date:

[linkdotnet]

That said, we might want to refactor:

<InputDate Type="InputDateType.DateTimeLocal" class="form-control" id="scheduled"
           placeholder="Scheduled Publish Date" @bind-Value="model.ScheduledPublishDate"
           @bind-Value:after="@(() => model.IsPublished &= !IsScheduled)" />

Away from the direct two-way-binding. Or transform this into UTC when creating the BlogPost object.

[linkdotnet]

Maybe also a low-hanging fruit you can implement:
Inside the CreateNewBlogPost.razor Page: Kann you add (in UTC) or similar to the Updated Date and Scheduled Publish Date in the UI?

So folks know it isn't there local time zone anymore

[EliasMasche]

Thanks for the info, I will check when I get to work again and see which option I picked.

[EliasMasche]

Hello there, I have been working with life stuff so now I am able to update ScheduledPublishDate for handling UTC, add a description on the GUI that all dates are saved as UTC on the DB and on CreateNewModel.cs to convert to LocalTime for displaying on the admin for the user convenience.

[linkdotnet]

Amazing - works like a charm!

I took the liberty to fix the merge conflict. In any case - I will merge that in! Really great work!
