Is it possible to export from a SQLite database?

[averri]

I'm running a SQLite database in memory, with URL sqlite://.

While the SQLite database is still open, invoking the following code:

db-to-sqlite sqlite:// database_copy.db --all --no-index-fks

... produces an output file database_copy.db which is not recognized as a SQLite database.

I'm using db-to-sqlite version 1.1.5.
