commit    fd1cf9d8407589fae354e1a5b852f33eedc7f67f

    Add valgrind suppressions for python code.
    
    Python's allocator does some low-level tricks for efficiency;
    unfortunately they trigger valgrind errors. Those tricks can be disabled
    making instrumentation easier; but few people testing postgres will have
    such a build of python. So add broad suppressions of the resulting
    errors.
    
    See also https://svn.python.org/projects/python/trunk/Misc/README.valgrind
    
    This possibly will suppress valid errors, but without it it's basically
    impossible to use valgrind with plpython code.

    Backpatch: 9.4, where we started to maintain valgrind suppressions
