Copy the relation name for error reporting in WCOs
In get_row_security_policies(), we need to make a copy of the relationname when building the WithCheckOptions structure, sinceRelationGetRelationName just returns a pointer into the local Relationstructure. The relation name in the WCO structure is only used forerror reporting.Pointed out by Robert and Christian Ullrich, who noted that thebuildfarm members with -DCLOBBER_CACHE_ALWAYS were failing.
