Nice catch Igor. Thanks. =) Will try and see if resolve can read that back in. Still very curious about the 3x slowdown in 9.5 pg_dump though. -- Henrik Cednert cto | compositor Filmlance International Basically, you are dumping 40GB of data. I’d say even 212 minutes under 8.4 version was too slow. What kind of RAID is it? RAID1/RAID10/RAID5? Regards, Igor Neyman
