Well, AIX 5.3 has been dead for over 6 years. You really shouldn't be doing any of this, it is just asking for trouble. Why not use a recent AIX with a recent PostgreSQL? If there is a running 9.3 installation on AIX 5.3 somewhere that you have to work with. upgrade ASAP by pg_dumping it with a recent PostgreSQL and importing into a new environment.
