title: password authentication failed for user "saleor"
body: <p>password authentication failed for user "saleor"
  FATAL: password authentication failed for user "saleor"</p>
  
  <p>when migrating the first time
   if it's something related  to database  please someone help me to figure this out
  I'm using Postgres  as the saleor documentation  says but I can't pass this migrations point 
  I read somewhere I have to create a database called saleor with saleor as a user with password 'saleor' who is a superuser and if that is the solution tell me how to do that</p>
