# When the generate_series virtual table is compiled for the testfixture,
# the special -DSQLITE_SERIES_CONSTRAINT_VERIFY=1 option is used, which
# causes the xBestIndex method of generate_series to leave the
# sqlite3_index_constraint_usage.omit flag set to 0, which should cause
# the SQLite core to verify the start=, stop=, and step= constraints on
# each step of output. At one point, the IN operator could not be used
# by virtual tables unless omit was set.
