Comment (by Zackary Troop):

 Small tweak in the introspection.py in the sqlite3 backend will fix this.
 I can setup the PR tonight.
 {{{
 >>> for field_desc in fields_sql.split(','):
 ...     field_desc = field_desc.strip()
 ...     m = re.match(r"(\w+).*PRIMARY KEY(?: AUTOINCREMENT)?.*",
 field_desc)
 ...     if m:
 ...             print(m.group(1))
 ...
 id
 }}}
