title: postgres equivilent of oracle sqlplus "set echo on"
body: <p>Is there an equivalent in PostgreSQL of the Oracle SQLPLUS "set echo on" so that I can get batch input
  statements echoed in the output?  </p>
  
  <p>I have a very large file with input statements in it that has a few errors when I run it. 
  I am having difficulty finding the statement that produced the error because psql is only reporting 
  the error - not the statement that generated the error.</p>
