The new test proposed by v4-0003 is increasing the vacuum_parallel.sql
timing by more than 10 times. It appears to be taking the highest time
among all the tests in make check. I think it is because of a large
amount of data being processed by the test. I think it is good to use
it for testing of patches during development but won't be a good idea
to commit. Can we reduce its timings?
