title: List stored functions that reference a table in PostgreSQL
body: <p>Just a quick and simple question: in PostgreSQL, how do you list the names of all stored functions/stored procedures using a table using just a SELECT statement, if possible? If a simple SELECT is insufficient, I can make do with a stored function.</p>
  
  <p>My question, I think, is somewhat similar to this other question, but this other question is for SQL Server 2005:<br>
  <a href="https://stackoverflow.com/questions/119679/list-of-stored-procedure-from-table">List of Stored Procedure from Table</a></p>
  
  <p>(optional) For that matter, how do you also list the triggers and constraints that use the same table in the same manner?</p>
