Hey Jeff,Andrew,
I continued testing the 12version vs the 96 version and it seems that there is almost non diff and in some cases pg96 is faster than 12. I compared the content of pg_stat_statements after each test that I have done and it seems that the db time is almost the same and sometimes 96 is faster by 5%.
Any idea why there isnt any improvement even when I enabled the parallel params in 12 ?
I can add a few examples if needed..
