Subject: [PATCHES] 970417:  two more patches for large objects

Here are two more patches:

        1.  pg_getint doesn't properly set the status flag when
            calling pqGetShort or pqGetLong.  This is required when
            accessing large objects via libpq.  This, combined with
            problem 1 above causes postgres to crash when postgres
            tries to print out the message that the status was not
            good.

        2.  ExceptionalCondition crashes when called with detail =
            NULL.  This patch prevents dereferencing the NULL.
