I just ran a performance test on my laptop with minimal configuration, it didn't show much
improvement, currently I don't have access to a big machine to test the performance.
I started reviewing the patch, during this process and I ran the regressiontest on the WARM patch. I observed a failure in create_index test.This may be a bug in code or expected that needs to be corrected.Can you please share the diff? I ran regression after applying patch on the current master and did not find any change? Does it happen consistently?
Yes, it is happening consistently. I ran the make installcheck. Attached the regression.diffs file with the failed test.
I applied the previous warm patch on this commit -
