can you make small extraction of this file (~ 100 rows), zip to file and
send to me off list?  I'll test it vs. a 2000 and xp server and try to
reproduce your results.

How are you dumping out your archive?  I confirmed unreasonably slow dump with pg_dump -Z temp2 > temp2.bkp on windows
2000server.  I normally use bzip to compress my dumps. 

Can you measure time to dump uncompressed and also with bzip and compare?

oops...cancel that.  I was dumping the wrong database. Dumping your
table from localhost on a dual Opteron win2k server took a few seconds
with Z=0 and Z=9.
