If sqlite3_column_text() and sqlite3_column_blob() return NULL and sqlite3_errcode() returns SQLITE_NOMEM, we should raise MemoryError and bail.

Quoting from the SQLite docs:
"As long as the input parameters are correct, these routines will only fail if an out-of-memory error occurs during a format conversion"
