How you intend to do that, exactly?  The bug is that it won't let you
write on /dev/tty, which puts a pretty severe crimp on *any* reporting.

(This is not as insane as it sounds: it's a reasonable security
restriction for a daemon process.  The error in older SELinux policy
files is that they think all the Postgres executables are daemons, not
only the postmaster.)
