Thanks, committed.

I thought about this. We don't have a man page for pg_regress, so there
is no place to comprehensively document all the options and their
interactions. The documentation in regress.sgml works on a makefile
level. AFAICT, the --debug option is not exposed via the makefiles at
all, while --no-locale can be requested by the environment variable
NOLOCALE, but that is not documented, and also not ported to meson. I
think if you want tweaks on this level, there is some expectations right
now that you might need to study the source code a bit.

One thing that might be interesting would be to allow running initdb
without the --no-sync option, to exercise fsync a bit. But there is no
"--yes-sync" option to override --no-sync, otherwise you could do it
with the just-committed feature.
