Indeed, initdb is going to remove the data directory if the bootstrap run
crashes.
If we do anything at all about this, my thought would just be to change
bootstrap_signals() so that it points all the signal handlers at
quickdie(), or maybe something equivalent to quickdie() but printing
a more apropos message, or even just set them all to SIGDFL since that
means process termination for all of these. die() isn't really the right
thing, precisely because it thinks it can trigger transaction abort,
which makes no sense in bootstrap mode.
But ... that code's been like that for decades and nobody's complained
before. Why are we worried about bootstrap's response to signals at all?
