Adding columns is directly supported. Removing columns, or redefining
them, is done with a CREATE TABLE AS/DROP TABLE/CREATE TABLE AS/DROP
TABLE sequence, where you write the columns you want to retain into a
temporary table, delete the original table, and then do the same back
into a new table with the same name as the original.

Good luck.
