Opening relations with no lock seems illegal to me.
Though I have no evidence that it does wrong thing
in ri_triggers.c,it seems that we had better acquire
an AccessShareLock on trial.
I sometimes see SEGV error around ri stuff and
I've doubted opening relations with no lock.
However the cause was different from it.
