title: Connect a MSSQL created database with PostgreSQL
body: <p>I use Mac and PostgreSQL is the choice for db management. I can not install MSSQL. There's a db which is created and managed by MSSQL. 
  I must not copy the entire data via a script, to my database (because of using real time data)
  My only option is, connecting that MSSQL created db with PostgreSQL.</p>
  
  <p>Is it possible? If yes, how? Will there be any relevant limitations for my queries?
  Thanks.</p>
  
  <p>Additional details:</p>
  
  <p>I'll make selections, calculations, statistically. 
  I won't modify the existing data.</p>
