I'd agree with trying to use the latest version you can.

How are you loading this data?  I'd make sure you haven't got any indices,
primary keys, triggers or constraints on your tables before you begin the
initial load, just add them after.  Also use either the COPY command for
loading, or prepared transactions.  Individual insert commands will just
take way too long.
