Increment of in-memory database size

[Gilwe]

Is there a way to utilize configurations like in https://www.sqlite.org/c3ref/c_config_covering_index_scan.html ? I want to know if I can run SQLite on going while setting SQLITE_MEMDB_DEFAULT_MAXSIZE.

Alternatively I would like to be able to run sqlite3_config() as I understand this needs to be done before db init.

Thank you.
