Unclear why this patch is getting rid of all the LOG_ERROR(). You can both LOG_ERROR AND return a useful IDBError. Why trade one for the other?

Why is it named Statement and not schema like it used to be? If I see statement, I expect a SQLiteStatement.

wouldn't `return { };` work?

> Source/WebCore/Modules/indexeddb/server/SQLiteIDBBackingStore.cpp:267
> +        return IDBError { };

wouldn't `return { };` work?

wouldn't `return { };` work?

As the error is more detailed, we can add error logging at higher level.
Will add logging in UniqueIDBDatabase::performCurrentOpenOperation().

I think schema is for describing the whole database and this is a column of an entry in schema table, which is usually text of the original statement to create the table.

No, chosen constructor is explicit in copy-initialization. (IDBError's constructor is explicit, we may change that)
