Re: Test 041_checkpoint_at_promote.pl faild in installcheck due to missing injection_points

By the way, we have the same kind of "problem" with the meson build. As we are deliberately 

not want to install src/test/modules, after b6a0d469cae and 0d237aeebaee we must add step 

"meson compile install-test-files" in order to "meson test -q --setup running" to be successful.

To be honest, this step is not obvious. Especially than there was no such step before. But 

docs and https://wiki.postgresql.org/wiki/Meson are completely silenced about it.
