Drupal 8.x

I am setting up Drupal 8.2.6 with postgres and the drupal installer fails with this error. I dont run into this issue when using MySQL though. Can someone help what might cause this to fail for Postgres + Drupal case.

Error:
The website encountered an unexpected error. Please try again later.
Drupal\Component\Plugin\Exception\PluginNotFoundException: The "field_storage_config" entity type does not exist. in Drupal\Core\Entity\EntityTypeManager->getDefinition() (line 133 of core\lib\Drupal\Core\Entity\EntityTypeManager.php).

In Drupal 7 I was able to have unpublished content displayed in a view and in Drupal 8 I am not just not able no matter what I do to get it to work the same way.

I have under ADVANCED in views disabled SQL rewriting in query settings, set access restrictions to none under PAGE SETTINGS, taken all filter criteria out that involves published status, and interestingly enough if I filter for yes or no on published or not in filter criteria makes no difference unpublished content will just not show up. I've been at it for two weeks now.

I wanted to create a flag link in one of my template file. If in php, what I have to follow is as below:

flag_create_link('bookmarks', $node->nid);

What would be the right approach to do the same in D8 with twig?

Hi guys,

I'm stuck on this weird issue on creating Rest APIs with Drupal 8.

The problem is that while I can make request to a GET endpoint and receive the correct response, the POST endpoint responds with an error message of "message": "No route found for \"POST /custom_practise_module/custom_api\": Method Not Allowed (Allow: GET, HEAD)"

Headers I passed with the requests includes Content-Type, X-CSRF-Token(got from rest/session/token), authorisation.
The REST resources have been enabled by REST UI for both the GET and POST methods.
