Interesting. I wonder, what is the impact on recovery time under the same conditions? I suppose that the cost of the random I/O involved would probably dominate just as with compress_backup_block = off. That said, you've used an SSD here, so perhaps not. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
