title: DROP FUNCTION without knowing the number/type of parameters?
body: <p>I keep all my functions in a text file with <code>'CREATE OR REPLACE FUNCTION somefunction'</code>.<br />
  So if I add or change some function I just feed the file to psql.</p>
  <p>Now if I add or remove parameters to an existing function, it creates an overload with the same name and to delete the original I need type in all the parameter types in the exact order which is kind of tedious.</p>
  <p>Is there some kind of wildcard I can use to <code>DROP</code> all functions with a given name so I can just add <code>DROP FUNCTION</code> lines to the top of my file?</p>
