Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.

Setup

installation, Ubuntu

// Return JSON without Jackson mapping classes
@RequestMapping("/users") 
public @ResponseBody Map<String, String> getUsers () {
    
  Map<String, String> map = new HashMap<String, String>();
  map.put("user", "Clark Kent");
    
  return map;
}
