** CAPI3REF: Add a Schema to a Changegroup
** METHOD: sqlite3_changegroup_schema
**
** This method may be used to optionally enforce the rule that the changesets
** added to the changegroup handle must match the schema of database zDb
** ("main", "temp", or the name of an attached database). If
** sqlite3changegroup_add() is called to add a changeset that is not compatible
** with the configured schema, SQLITE_SCHEMA is returned and the changegroup
** object is left in an undefined state.
**
** A changeset schema is considered compatible with the database schema in
** the same way as for sqlite3changeset_apply(). Specifically, for each
** table in the changeset, there exists a database table with:
**
** <ul>
** <li> The name identified by the changeset, and
** <li> at least as many columns as recorded in the changeset, and
** <li> the primary key columns in the same position as recorded in
** the changeset.
** </ul>
**
** The output of the changegroup object always has the same schema as the
** database nominated using this function. In cases where changesets passed
** to sqlite3changegroup_add() have fewer columns than the corresponding table
** in the database schema, these are filled in using the default column
** values from the database schema. This makes it possible to combined
** changesets that have different numbers of columns for a single table
** within a changegroup, provided that they are otherwise compatible.
