the sqlite_dbpage, sqlite_dbdata, and sqlite_dbptr virtual tables to make
use of that interface. This was formerly handled by the internal
sqlite3VtabUsesAllSchemas() routine that was called directly from sqlite_dbpage.
But since sqlite_dbdata and sqlite_dbptr are an extension, an external
interface to that functionality had to be provided.

(1) Do not allow a RETURNING clause to trick the code generator into thinking
that the view being updated has an INSTEAD OF trigger.
(2) Generate all result columns for a view in a DML statement.
(3) The automatic covering index for a view should cover all result columns
of the view.

fix for [forum:/forumpost/07de5f6216|forum post 07de5f6216]. The register
allocation logic in ANALYZE needs to be completely refactored, but that will
