event_triggers — PostgreSQL configuration parameter

Allow temporarily disabling execution of event triggers in order to troubleshoot and repair faulty event triggers.

At a glance

What it does

Allow temporarily disabling execution of event triggers in order to troubleshoot and repair faulty event triggers. All event triggers will be disabled by setting it to false. Setting the value to true allows all event triggers to fire, this is the default value. Only superusers and users with the appropriate SET privilege can change this setting.

(Description quoted from the official PostgreSQL documentation.)

How to apply a change

Can be set per session with SET, per role/database with ALTER ROLE/DATABASE ... SET, or globally in postgresql.conf.

Inspect the current value and source with SHOW event_triggers; or SELECT name, setting, unit, context, source FROM pg_settings WHERE name = 'event_triggers';.

Tuning guidance

This sets a session default (locale, formatting, search path or transaction behaviour) rather than a performance knob. Set it per role or database with ALTER ROLE/DATABASE ... SET so the right default follows the right workload, and prefer setting it explicitly in the application for behaviour the query results depend on.
