+** This file contains an implementation of the "sqlite_dbpage" virtual table.
+**
+** The sqlite_dbpage virtual table is used to read or write whole raw

+** uncommitted changes and changes recorded in the WAL file are correctly
+** retrieved.
+**
+** Usage example:
+**
+** SELECT data FROM sqlite_dbpage('aux1') WHERE pgno=123;
+**
+** This is an eponymous virtual table so it does not need to be created before
+** use. The optional argument to the sqlite_dbpage() table name is the
+** schema for the database file that is to be read. The default schema is
+** "main".
+**
+** The data field of sqlite_dbpage table can be updated. The new
+** value must be a BLOB which is the correct page size, otherwise the
+** update fails. Rows may not be deleted or inserted.
