problem is not coming from psql.

One thing I did notice that in a 250k insert transaction the insert time
grows with #recs inserted.  Time to insert first 50k recs is about 27
sec and last 50 k recs is 77 sec.  I also confimed that size of table is
not playing a role here.

Marc, can you do select timeofday() every 50k recs from linux?  Also a
gprof trace from linux would be helpful.
