Hi Marti, The parameter statement_timeout isn't configured.. I'm using the value default.. 0.. And this is happening when I'm doing large querys on the slave.. thanks, Tulio Em 01/02/2012 12:33, Marti Raudsepp escreveu: On Mon, Jan 30, 2012 at 20:55, Tulio <tulio@xxxxxxxxxxxxxxxxx> wrote:I have 2 servers, working with Hot-Standby and Streaming Replication... and when we executed some query much large returns a message.. "canceling statement due to statement timeout" I want know, how can I calculate the better value to "vacuum_defer_cleanup_age" in my case?This error doesn't happen due to recovery conflict, so vacuum_defer_cleanup_age doesn't make any difference. The error happens because the statement_timeout setting is configured somewhere (maybe per-database or per-user settings). Set it to 0 to disable the statement timeout. Regards, Marti |
