Thanks much! That met with partial success; but getting closer.
The error message about OLD went away (thankfully!), but there is still no data from the OLD variable. Here is the code again:
create trigger PEDIGREES_hist_del_trig
AFTER DELETE
on PEDIGREES
FOR EACH ROW
EXECUTE PROCEDURE logPedigreesDel();
CREATE OR REPLACE FUNCTION logPedigreesDel() RETURNS TRIGGER AS '
begin
RAISE EXCEPTION ''OLD.famindid = '', OLD.famindid;
return OLD;
end;
' LANGUAGE plpgsql;
Which when it fires results in:
cgb_lab_data=# \i testphdtrig.sql
psql:testphdtrig.sql:1: ERROR: OLD.famindid = Regards,

I think you forgot FOR EACH ROW. By default, the above creates a
STATEMENT trigger, in which you don't have access to individual rows.
