Before running pg_resetxlog, a couple of questions:

1. Since it appears that pg_control is suspect, should I force it to be   rebuilt, and if so, how?

2. At the end of GuessControlValues is this comment:  /*   * XXX eventually, should try to grovel through old XLOG to
develop  * more accurate values for startupid, nextXID, and nextOID.   */   What would be involved in doing this, and
doyou think it would be   worth it?
 

Thanks,
