Good catch.

It'd probably be best to strdup() argv[0], because of the likelihood
that the argv area will get clobbered at some point by ps_status.c.
It was OK to have a private static in postmaster.c, because the
postmaster doesn't ever call ps_status.c, but if we are going to expose
the variable in child processes it needs to be more globally valid.

I see that get_progname strdup's its argument in some cases but not
all --- so simplest fix is to make it always do so.
