;; This file contains code to set up Emacs to edit PostgreSQL source
;; code.  Copy these snippets into your .emacs file or equivalent, or
;; use load-file to load this file directly.
;;
;; Note also that there is a .dir-locals.el file at the top of the
;; PostgreSQL source tree, which contains many of the settings shown
;; here.  So for light editing, you might not need any additional
;; Emacs configuration.
