The failure occurs while trying to emit an ALTER SEQUENCE OWNED BY
command to link the sequence to its owning serial column. If we chose
not to dump the parent table then we won't have collected enough
information about it to create this command (specifically, we never
fetched its column names).
The definitional question is: if we selected only the sequence to dump,
do we want that ALTER command to appear in the output or not? It's a
reasonably straightforward fix either way (a bit easier for "not"),
but I'm unsure which is the most useful behavior.
