The PostgreSQL documentation contains this recommendation: "Ideally the setting should exceed your typical transaction time ". On large systems, consider increasing the deadlock_timeout setting. This can lead to performance degradation on bigger systems, where it can be normal for queries to wait for more than 1 second during load times. This means every time a query waits on a lock for more than 1 second, PostgreSQL will launch a check for deadlock condition and will log an error if the logging setting has been configured that way (by default, it is). log_truncate_on_rotation = on (enable log file overwrite)īy default, the deadlock_timeout setting in the nf file is configured to 1 second.(setting is disabled to prevent the overwriting of the daily log file every time this limit is exceeded) log_rotation_age = 1440 (a new log file is created daily).log_filename = 'postgresql-%a.log' (every log file has the first 3 letters of the weekday in its name).There are several combinations of parameters that you can use to achieve a log rotation to suit your requirements. When log_truncate_on_rotation is set to "on", it will overwrite any log file that has the same name as a newly created log file. You can use time and date format conversion in the name. Log_filename controls the name given to every log file. For example, setting log_rotation_age to 1440 will create a new log file every 1440 minutes (1 day), and setting log_rotation_size to 10000 will create a new log file when the previous one reaches 10 000 KB. Log_rotation_age and log_rotation_size control when a new log file is created. When using PostgreSQL with Deep Security, we recommend that you use these four parameters in the nf file to configure log rotation: Tuning PostgreSQL settings Logging settingsīy default, PostgreSQL log files are not rotated, which can lead to the log files using a large amount of disk space. If you need additional help, PostgreSQL offers professional support. When fine tuning performance, verify settings by monitoring your database IOPS with a service such as Amazon CloudWatch. To change settings, use database parameter groups and then restart the database instance. Often, you only need to fine tune autovacuuming, max_connections and effective_cache_size. Amazon Aurora: Defaults vary by instance size.Amazon RDS: Defaults vary by instance size.In a plain text editor, open the nf file.Some defaults are not appropriate for data center or customized cloud installs, especially in larger deployments. Self-hosted database: Defaults are generic values from the PostgreSQL core distribution.
