Well tuptoaster doesn't try to store anything external if there's no toast
table anyways. With the assertion modified it passes the regression tests
(modulo row orderings).

This was 1k with 256 toast target/threshold.
If I push the TOAST_TUPLES_PER_PAGE up to 16 I get another failure on the same
line from trying to toast a sequence. If I add RELKIND_SEQUENCE to the
assertion then it passes all regression tests even if I push
TOAST_TUPLES_PER_PAGE up to 1024 -- ie, try to toast everything as far as
possible. Perhaps heapam.c:1761 should just check for RELKIND_SEQUENCE as
well.
