Title: The todb and appenddb do not work with psycopg2 adapter.

The backtick quoting character ` is not standard and not supported on all databases.
The recommended quoting character is ".

The double-quote for identifiers is supported by PostgreSQL and SQLite out-of-the-box.
For MySQL and other databases, some global switches are available to conform to standard SQL-92.
