I was planning to use the sqlite3_update_hook function to notify my GUI

Yes it would appear that the file is open read only. I cannot open the file in

"Experimental" means that we reserve the right to change it in
future releases
Make the hook queue a GUI update transaction and execute those
transactions following the COMMIT. Discard the list of GUI update
transactions on a ROLLBACK.

Is there any chance of getting an international-aware case-insensitive
collation option put into the core language, at least as a compilation
option? Seems that if SQLite is so focused on UTF data and so many users
are international, the limitation of available options being English A-Z
But what about:
I am very interested to know if it would be possible to use an FTS indexing
module to store the inverted index only, but
not the document's text. This would safe disk space if the text to index is
stored on disk rather than inside the database.

If ask the table sturcture, with pragma table_info()
I get of course the basic fields, like:

And also SOME special values, like
Null, DefaultValue, PrimaryKey
But NOT the following special values (and probably a lot more)
Unique, AutoIncrement
Is this due to the DLL I use,

3.3.13 typically generates database files that are 30-40% smaller
than 2.8.16. 60% seems excessive, but is not outside the range of
possibility. What kind of data

Don't know about "normal" but ISTR version 3 did bring some fairly major
improvements in file size. Given that you have your data in both SQLite
formats would it not be fairly easy to dump both
