Shared cache mode does not apply to :memory: databases. It is not

REPLACE INTO doesn't change records. It replaces them. W
I think with a virtual table all you can do is:
SELECT * FROM vtable WHERE x = 'a' UNION
SELECT * FROM vtable WHERE x = 'b'
Virtual tables cannot supply an index for WHERE clauses of the form
"x IN ('a', 'b')" or "x = 'a' OR x = 'b'" the way normal tables
can.

For pager pragmas not specifying a database where it is optional is
; like ':memory:2'? Nothing that I've tried works.

The basic rule is that the result of any comparison involving a
NULL value (including comparing against another NULL) is NULL.
See the following for the details:

Right. Each thread has to have it's own sqlite3* handle.

I don't think so. The master journal file is created (and also
deleted, unless a crash occurs) during the final commit
processing (i.e. during sqlite3_step() of COMMIT). Up until
that point there's no special processing for multi-database
transactions.

What sqlite versions, OS etc.? This worked for me:
$ sqlite3
SQLite version 3.2.8
Enter ".help" for instructions

$ cat out.txt

To my knowledge SQLite can only store text using UTF-8 or UTF-16
encoding.
I guess in some circumstances the latin1 representation
would be more compact than UTF-8, but if that's an issue for
you then you would probably want to apply some kind of external
compression algorithm to your strings an
