Please note that the new patch still gives assertion error:
TRAP: FailedAssertion("!(buf->freeNext != (-2))", File: "freelist.c", Line:
178)
psql:load_test.sql:5: connection to server was lost
Hence, the patch was installed with assertions off.
I also ran the test script after making the same configuration changes that
you have specified. I found that I was not able to get the same performance
difference that you have reported.
Following table lists the tps in each scenario and the % increase in
performance.

Kindly let me know if I am missing something.
