Clean up pg_dump coredumps caused by change of output formatting for

oidvector/int2vector.  pg_dump code was assuming that it would see
exactly FUNC_MAX_ARGS integers in the string returned by the backend.
That's no longer true.  (Perhaps that change wasn't such a good idea
after all --- will it break any other applications??)
