2675 To make things even more complicated, there may be other chat messages waiting to be send.
2676 
2677 We used the following approach:
2678 1. If we do not need to send a message, we delete the chat directly
2679 2. If we need to send a message, we set chats.blocked=1 and add the parameter
2680  MRP_DEL_AFTER_SEND with a random value to both, the last message to be send and to the
2681  chat (we would use msg_id, however, we may not get this in time)
2682 3. When the messag with the MRP_DEL_AFTER_SEND-value of the chat was send to IMAP, we physically
2683  delete the chat.
2684 
2685 However, from 2017-11-02, we do not implicitly leave the group as this results in different behaviours to normal
2686 chat and _only_ leaving a group is also a valid usecase. */

27 
28 - `PRAGMA cache_size` and `PRAGMA page_size`: As we save BLOBs in external
29  files, caching is not that important; we rely on the system defaults here
30  (normally 2 MB cache, 1 KB page size on sqlite < 3.12.0, 4 KB for newer
31  versions)
32 
33 - We use `sqlite3_last_insert_rowid()` to find out created records - for this
34  purpose, the primary ID has to be marked using `INTEGER PRIMARY KEY`, see
35  https://www.sqlite.org/c3ref/last_insert_rowid.html
36 
37 - Some words to the "param" fields: These fields contains a string with
38  additonal, named parameters which must not be accessed by a search and/or
39  are very seldomly used. Moreover, this allows smart minor database updates. */
