[ pokes around... ]  Ah, you're right, that stuff goes through
port->cmdline_options now.  It looks like the mechanism for -o
is the postmaster's ExtraOptions variable, which we could get
rid of this way.  Seems like a reasonable thing, especially since
we unified all the other postmaster/postgres options already.
