title: How can I get a list of all functions stored in the database of a particular schema in PostgreSQL?
body: <p>I want to be able to connect to a PostgreSQL database and find all of the functions for a particular schema.</p>
  
  <p>My thought was that I could make some query to pg_catalog or information_schema and get a list of all functions, but I can't figure out where the names and parameters are stored. I'm looking for a query that will give me the function name and the parameter types it takes (and what order it takes them in).</p>
  
  <p>Is there a way to do this?</p>
