We noticed a regression in Python3.10.0a6 (it works properly in Python3.10.0a5) when running Django's test suite. Empty bytestrings are not longer returned properly on SQLite:
Regression in 47feb1f
See https://bugs.python.org/issue43249
I will submit PR in few minutes.

sqlite3_column_blob() should be handled like sqlite3_value_blob() in #68862:
In case of NULL, check sqlite3_errcode() and raise MemoryError if needed. Else it's a zero-sized blob.

I created bpo-43369 for out-of-memory error handling, since it also applies to sqlite3_column_text().
