PostgresDB 09000: Triggered Action Exception

What is PostgresDB 09000: Triggered Action Exception

Identify the specific trigger causing the issue by running the following SQL command:

SELECT event_object_table, trigger_name, action_timing, event_manipulation, action_statementFROM information_schema.triggersWHERE trigger_schema NOT IN ('pg_catalog', 'information_schema');

Once you've identified the problematic trigger, examine its function for errors or unintended consequences by querying its definition:

SELECT pg_get_triggerdef(t.oid)FROM pg_trigger tJOIN pg_class c ON c.oid = t.tgrelidJOIN pg_namespace n ON n.oid = c.relnamespaceWHERE t.tgname = 'trigger_name_here'; -- replace trigger_name_here with the name of the trigger you're investigating

Check the PostgreSQL logs for any error messages related to the trigger. The log location can vary but can often be found in /var/log/postgresql/ or by running:

SHOW log_directory;

Temporarily disable the trigger to confirm it's the source of the issue. Warning: This should only be done if it's safe to temporarily disable the trigger without affecting the integrity or operation of your database:

ALTER TABLE table_name DISABLE TRIGGER trigger_name_here; -- Replace table_name and trigger_name_here accordingly.

Note: Before disabling a trigger, ensure you understand the implications, as this could affect data integrity or business logic enforced by the trigger.
