Interesting. Out of interest (if you still have it), what does pg_dump
think the schema looks like? It sounds like pgAdmin is misreading the
schema somehow, causing the crash - most likely when it tries to detect
the primary key. One thought - in the edit grid, did the int8 column
have [PK] in the column header?
