FWIW, the following worked fine for me:

#+name: my-query
#+header: :engine postgresql
#+header: :dbhost <host>
#+header: :dbuser <user>
#+header: :dbpassword <password>
#+header: :database sheetmusic
#+begin_src sql
  SELECT id, creator, title, category, boxnumber FROM music
  WHERE id > 300;
#+end_src

#+RESULTS: my-query
