What's not contrived about it? Particularly the case of *only* deleting
pg_control and not any other critical file? I don't recall having heard
any such stories in the last twenty years.
Also, even if we added the complexity needed to write data into say
pg_control.bak, what then? You think that that would be any less
prone to indiscriminate rm'ing? Where and how would we document this,
and what's the odds that someone dumb enough to remove pg_control would
ever have read that part of the documentation?
I'm with Andres: this is a solution in search of a problem.
