pg_trigger

Hi list,

I'm trying to extract references between tables. Here is the sql:

select
u.usename,
p.relname,
v.usename,
c.relname,
t.tgconstrname,
dumpref(t.tgargs, 4),
dumpref(t.tgargs, 5)
from
pg_trigger t,
pg_proc f,
pg_class p,
pg_class c,
pg_user u,
pg_user v
where 1=1
and f.proname='RI_FKey_check_ins'
and t.tgfoid=f.oid
and c.oid=t.tgrelid
and p.oid=t.tgconstrrelid
and u.usesysid=p.relowner
and v.usesysid=c.relowner;

I always the following message:

Error while executing the query;
ERROR: Function 'dumpref(bytea, int4)' does not exist
Unable to identify a function that satisfies the given argument
types
You may need to add explicit typecasts

What am I doing wrong ??
