+# Temporarily Disable Triggers
+
+In general, you are always going to want your triggers to fire. That's why
+they are there. Though special circumstances may arise where you need to
+temporarily disable them. Use
+
+```sql
+> set session_replication_role = 'replica';
+SET
+```
+
+By changing the
+[replication role](http://www.postgresql.org/docs/9.4/static/runtime-config-client.html#GUC-SESSION-REPLICATION-ROLE)
+from `origin` to
+`replica` you are essentially disabling all non-replica triggers across the
+database (for that session). When you are done, you can simply set the
+replication role back so that normal trigger behavior can resume
+
+```sql
+> set session_replication_role = 'origin';
+SET
+```
+
+A more direct and fine-grained approach to disabling triggers is to use an
+`alter table` command that targets a specific trigger.
