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.

My question, I think, is somewhat similar to this other question, but this other question is for SQL Server 2005:
List of Stored Procedure from Table

(optional) For that matter, how do you also list the triggers and constraints that use the same table in the same manner?
