# Test Organisation:
# ------------------
#
# alter4-1.*: Test that ALTER TABLE correctly modifies the CREATE TABLE sql.
# alter4-2.*: Test error messages.
# alter4-3.*: Test adding columns with default value NULL.
# alter4-4.*: Test adding columns with default values other than NULL.
# alter4-5.*: Test adding columns to tables in ATTACHed databases.
# alter4-6.*: Test that temp triggers are not accidentally dropped.
# alter4-7.*: Test that VACUUM resets the file-format.
