In any case the RI trigger firings will be postponed till end of query.
I suspect that the memory growth is due to the list of pending trigger
firings. The advice to add the REFERENCES constraint after you've
loaded the table seems good to me.
Another possibility is that there's some memory leak associated with the
txtidx data type; I dunno how thoroughly that type has been tested...
