You mean like this?

regression=# create table t1 (f1 int primary key);
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index 't1_pkey' for table 't1'
CREATE TABLE
regression=# create table t2 (f2 int references t1);
NOTICE:  CREATE TABLE will create implicit trigger(s) for FOREIGN KEY check(s)
CREATE TABLE
regression=# insert into t2 values(42);
ERROR:  $1 referential integrity violation - key (f2)=(42) referenced from t2 not found in t1
regression=#

I'm still wondering how to rephrase this to fit in the
recently-agreed-to message style guidelines.  I think the
(col names)=(values) part must go into errdetail, but I'm
fuzzy beyond that.  Comments?
