-   DROP COLUMN functionality was added in release 7.3 with ALTER TABLE
-   DROP COLUMN. In earlier versions, you can do this:
-    BEGIN;
-    LOCK TABLE old_table;
-    SELECT ...  -- select all columns but the one you want to remove
-    INTO TABLE new_table
-    FROM old_table;
-    DROP TABLE old_table;
-    ALTER TABLE new_table RENAME TO old_table;
-    COMMIT;

    Changing the data type of a column can be done easily in 8.0 and later
    with ALTER TABLE ALTER COLUMN TYPE.
