👍

Maybe we should remove the default case and error log so that we notice next time in case we introduce a new data type.

Why not use sqlite3_bind_blob ?

I don't know? Why use it? Currently all the QByteArray only contains text.

OK 👍 if you take the risk that if we ever change that something bad happens.
Although the function has a size parameter so maybe it's OK.
(And we anyway always get text from WebDAV)

Any other than a string was not working before because we were converting to QString anyway.
