Since setting certain pragmas may affect the SQL code generated from a
statement during sqlite3_prepare(), it is a good idea to have currently
prepared statements re-prepared via the expire opcode.

I suspect this doesn't happen because from an in-expert bit of poking,
I don't think PRAGMA commands "really" get compiled to VDBE (which is
what I believe "preparing" a statement does).
In the transcript below, although the _query_ seems to use VDBE (to
return the result in "p4", the two attempts
I’ve got a similar issue. I user user_version to store a .net version
object I’ve serialised as an int. I convert them to/from text to get them
in and out using the pragma. It would be a nice to have for pragmas to
support parameters.
Cheers

Hi,
I am using the user_version pragma for implementing an event-handling
database. I'd like to prepare the statement to update it, e.g. `PRAGMA
user_version = ?`.
However, sqlite3 won't let me do that, so I just run the text query every
time with the number embedded.
Not a huge problem, more of
Thank you.
