But this one is necessary as well to allow hot standby faster to initialize, no? Particularly in the case where a bgwriter snapshot would have been taken just before the checkpoint, there may be up to 15s until the next one. And AFAIK, this code would not get a back-patch, as stated by Andres upthread :( I would think that it is better to actually get a backpatch, but well... -- Michael -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
