##Basics

PostgreSQL & PL/pgSQL Stored Functions Cheatsheet

CREATE OR REPLACE FUNCTION public.sp_user_ins_status(status smallint)
  RETURNS integer
  LANGUAGE plpgsql
AS $function$

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
