[ Thread moved to hackers list.]
OK, this is exactly what I wanted to see, and it explains why pg_dump
didn't show it. Can you find out what table references this toast
table? Try this query on the old cluster:
select oid, * from pg_class WHERE reltoastrelid = 16439148;
I believe it will have an oid of 16439145, or it might not exist.
