The Z1 data set is posted at: http://people.ok.ubc.ca/rlawrenc/tpch1g1z.zip I have not generated Z2, Z3, Z4 for 1G, but I can generate the Z2 and Z3 data sets, and in a hour or two they will be at: http://people.ok.ubc.ca/rlawrenc/tpch1g2z.zip http://people.ok.ubc.ca/rlawrenc/tpch1g3z.zip Note that Z3 and Z4 are not really useful as the skew is extreme (98% of the probe relation covered by top 100 values). Using the Z2/Z3 data set should be enough to show the huge win if you do *really* have a skewed data set. BTW, is there any particular form/options of the pg_dump command that I should use to make the dump? -- Ramon Lawrence -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
