convert schema to table prefix automatically

[tcecyk]

What do you think about doing an automatic schema to table prefix conversion and logging an info notice to stdout? You allude to a schema rename / removal being necessary in your stackoverflow answer.

Even if only done for "public" automatically, the very common case, it would help most naive users, as the error message doesn't suggest it.

[SQLITE_ERROR] SQL error or missing database (no such table: public.example)

An alternative is outputting a warning within the Copy command if a schema is found. Would you accept a PR on this?

This is good idea, unfortunately have no time to do it. PR is welcomed.
