How can I find and see the code of a trigger automatically generated by a

You can get the parameters out of pg_trigger (if you've named your
constraint you can use tgconstrname to find them, otherwise you need to
compare items in tgargs).

The code itself is in C and is in src/backend/utils/adt/ri_triggers.c
