I would keep an eye on backend's mem usage, don't let them get out of memory
nor go to swap.
I would consider increasing wal_files, i think postmaster is telling you every
minute
hope it helps

Actually, checkpoint_segments is the critical parameter when you have
lots of activity and are checkpointing too often.  wal_files is longer
significant because we reuse WAL files.  I think it may be removed in
7.3 anyway.  I want to add this information to hardware performance
tuning paper.
