Thread: pgsql: Apply identity sequence values on COPY

Apply identity sequence values on COPY

A COPY into a table should apply identity sequence values just like it
does for ordinary defaults.  This was previously forgotten, leading to
null values being inserted, which in turn would fail because identity
columns have not-null constraints.
