** for all columns of the new.* or old.* record, respectively.
**
** * If the change is an UPDATE record, then values must be provided for
** the PRIMARY KEY columns of the old.* record, but must not be provided
** for PRIMARY KEY columns of the new.* record.
**
** * If the change is an UPDATE record, then for each non-PRIMARY KEY
** column in the old.* record for which a value has been provided, a
** value must also be provided for the same column in the new.* record.
** Similarly, for each non-PK column in the old.* record for which
** a value is not provided, a value must not be provided for the same
** column in the new.* record.
**
** * All values specified for PRIMARY KEY columns must be non-NULL.
**
** Otherwise, it is an error.
**
** If the changegroup already contains a change for the same row (identified
** by PRIMARY KEY columns), then the current change is combined with the
** existing change in the same way as for sqlite3changegroup_add().
**
** For a patchset, all of the above rules apply except that it doesn't matter
** whether or not values are provided for the non-PK old.* record columns
** for an UPDATE or DELETE change. This means that code used to produce
** a changeset using the sqlite3changegroup_change_xxx() APIs may also
** be used to produce patchsets.
**
** If the call is successful, SQLITE_OK is returned. Otherwise, if an error
** occurs, an SQLite error code is returned. If an error is returned and
** parameter pzErr is not NULL, then (*pzErr) may be set to point to a buffer
** containing a nul-terminated, utf-8 encoded, English language error message.
** It is the responsibility of the caller to eventually free any such error
** message buffer using sqlite3_free().
