ban-add-column

problem

Adding a column to an existing table or foreign table changes the shape of SELECT * results and can break positional inserts from existing clients. This rule is opt-in. An unconditional CREATE TABLE earlier in the file suppresses a warning for that new table.

ALTER TABLE accounts ADD COLUMN status text;

solution

Check clients that use SELECT * or positional inserts before adding the column.

Enable this rule with --include ban-add-column.
