That would be satisfactory to me. However, I'm sure some will cringe at
a MySQL-like configurable integrity option. Might it be better as an
initdb-time option? I can't think why anyone would want to change it
later.

I prefer this option. It's consistent with the docs, which say:

"The SQL_ASCII setting behaves considerably differently from the other
settings,"
and also
"One way to use multiple encodings safely is to set the locale to C or
POSIX during initdb, thus disabling any real locale awareness."
