Done, and here's the results: Traditional way (-DCLOBBER_CACHE_ALWAYS): 32:53:24 https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=sifaka&dt=2021-07-01%2018%3A06%3A09 New way: 16:15:43 https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=sifaka&dt=2021-07-03%2004%3A02%3A16 That's running sifaka's full test schedule including TAP tests, which ordinarily takes it a shade under 10 minutes. The savings on a non-TAP run would be a lot less, of course, thanks to fewer initdb invocations. Although I lacked the patience to run a full back-branch cycle with -DCLOBBER_CACHE_ALWAYS, I did verify that the patch correctly injects that #define when running an old branch. So I think it's ready to go into the buildfarm, modulo any cosmetic work you might want to do. regards, tom lane
