The changes aren't actually that big.  The major difference is that SQLite
version 2 stored all values as strings and would try to convert to other
types as appropriate.  Version 3 uses manifest typing.

While the core functionality was very similar (ie making queries and getting
values), SQLite 3 has added more non-query functionality like virtual
tables, VFS, blob I/O, backup API, FTS, Rtree, ICU etc.

No it can't.  The file formats are different.
