Comment (by rhertzog):
You are both correct AFAIK.
But if you do what shaib suggest, then the unit test is only useful on
systems where SQLITE_MAX_VARIABLE_NUMBER has been increased. I would
suggest that maybe two tests are warranted, one to verify that the the
quoting function does it by batches (whatever configuration is in place)
and one to test we can have many values in a real query run through the
ORM if sqlite does accept many parameters.
