One more comment on this: I wonder if the field isn't incremented too
early. It seems to me that the value can end up non-zero if the input set is
to be empty (not sure if it can happen in practice).
And finally one question about regression tests: what's the purpose of the
changes in contrib/postgres_fdw/sql/postgres_fdw.sql ? I see no
IncrementalSort node in the output.
