 No, why ?

 I can define a method conditionnaly, and if I retrieve a class not written
 by me what do I do ? I don't even know what methods are defined.

n> # test.rb
n> autoload :PLruby, "pltest.o"
n> autoload :PLtemp, "pltest.o"
n> puts PLruby, PLtemp

 You can't write this script because $SAFE >= 4 (plruby will not execute
 it) 

 plruby is loaded by postgres *before* any script is executed, and a script
 is executed with $SAFE >= 4

 The test that it make actually is in the case where it run in a very
 strange environnement. Normally the test is always false (PLruby and
 PLTemp are not defined by ruby), if these constants exist this mean that
 there is something strange, and in this case I prefer stop rather than
 retrieving old methods.
