  **        type       text,    --  Either "table" or "index"

  **        sql        text     --  The CREATE statement for this object
  **    );
  **
  ** The sqlite_master table contains a single entry for each table
  ** and each index.  The "type" column tells whether the entry is
  ** a table or index.  The "name" column is the name of the object.
  ** The "tbl_name" is the name of the associated table.  For tables,
  ** the tbl_name column is always the same as name.  For indices, the
  ** tbl_name column contains the name of the table that the index
  ** indexes.  Finally, the "sql" column contains the complete text of
  ** the CREATE TABLE or CREATE INDEX statement that originally created
  ** the table or index.
  **
  ** If the "type" column has the value "meta", then the "sql" column
  ** contains extra information about the database, such as the
  ** file format version number.  All meta information must be processed
  ** before any tables or indices are constructed.
  **
  ** The following program invokes its callback on the SQL for each
  ** table then goes back and invokes the callback on the
  ** SQL for each index.  The callback will invoke the
  ** parser to build the internal representation of the
  ** database scheme.
