Thanks for updating the patch! LGTM.

Just one small comment:

+Hayward 37 54 0.0 1994-11-29

This row is inserted using the following INSERT statement:

INSERT INTO weather (date, city, temp_hi, temp_lo)
VALUES ('1994-11-29', 'Hayward', 54, 37);

Since the prcp column isn't specified, its value is NULL. So shouldn't
the fourth field in the data line above be \N instead of 0.0?
