RI_ConstraintTrigger question - Mailing list pgsql-general

We have a database with about 30 tables and some RI. The RI constraints,
however, were not named upon creation of the database 2-3 years ago and
now when we get an error it contains <unnamed> for the constraint.

I tried Google and the documentation, and I still have 2 questions -

1. Is it possible to rename RI_ConstraintTrigger, so that we do not get
<unnamed> in the errors.

2. Is there somewhere explanation what the RI_FKey_ procedures mean?

Thanks you.
