Look at the pg_trigger table. There is some documentation on what the various
fields mean.
Normally, I see these triggers when I have declared a table to have a foreign
key, or I created a table that has a foreign key that references this table.
I can usually decode who is referencing what from the tgargs column.
Example:
<unnamed>\000order_materials\000order_shipping\000UNSPECIFIED\000order_ship_id\000order_ship_id\000
Translates to:
order_materials.order_ship_id references order_shipping.order_ship_id
I have found a ton of these as I have upgraded from 7.2 to 7.3. I have dropped
most of the triggers and altered the table to have the foreign keys to remedy
this.
