CI/CD pipeline with PostgreSQL failed with "Database is uninitialized and superuser password is not specified" error : <p>I'm using Bitbucket pipeline with PosgreSQL for CI/CD. According to this <a href="https://confluence.atlassian.com/bitbucket/test-with-databases-in-bitbucket-pipelines-856697462.html" rel="noreferrer">documentation</a> PostgreSQL service has been described in <code>bitbucket-pipelines.yml</code> this way:</p>

<pre><code>definitions:
  services:
    postgres:
      image: postgres:9.6-alpine
</code></pre>

<p>It worked just fine until now. But all my latest pipelines failed with following error:</p>

<pre><code>   Error: Database is uninitialized and superuser password is not specified.
   You must specify POSTGRES_PASSWORD for the superuser. Use
   "-e POSTGRES_PASSWORD=password" to set it in "docker run".

   You may also use POSTGRES_HOST_AUTH_METHOD=trust to allow all connections
   without a password. This is *not* recommended. See PostgreSQL
   documentation about "trust":
   https://www.postgresql.org/docs/current/auth-trust.html
</code></pre>

<p>How can I fix it? There was no changes in <code>bitbucket-pipelines.yml</code> file which could be the reason of such error..</p>
