This change would be especially handy for dealing with those
cases in multipath/pgpolicies.c. There are several functions
in that file that exit(1) on error, rather than returning a
failure status.
This means that whenever these errors occur, the multipath.run file
is left behind.
I'm also wondering whether you really want these failure cases to
just exit() on error.
