title: Show Sql in Jhipster 4.4.1
body: <p>I added a new connection to my Jhipster application:  </p>
  
  <pre><code>data:
      mongodb:
          uri: mongodb://localhost:27017
          database: crm
  datasources:    
      elser:
          driver-class-name: org.postgresql.Driver
          url: jdbc:postgresql://localhost:5432/elser
          name: elser
          username: elser
          password: elser
  </code></pre>
  
  <p>I want to see in the sql logs that my connection to Postgres generates.</p>
  
  <p>I have tested by adding the following code in 'application-dev.yml':</p>
  
  <pre><code>jpa:
    properties:
      hibernate:
        show_sql: true
        format_sql: true
  </code></pre>
  
  <p>or:</p>
  
  <pre><code>jpa:
      show_sql: true
      format_sql: true
  </code></pre>
  
  <p>But neither option worked for me. </p>
  
  <p>Can somebody help me. </p>
  
  <p>Thank you</p>
