I know of no book specifically on PostgreSQL. For SQL, a very good book
is "The Practical SQL Handbook" by Bowman, Emerson and Darnovsky,
ISBN 0-201-44787-8.

The command for changing columns in a table is ALTER TABLE. At present,
there is no facility to drop columns.
Create a new table with the correct columns; copy from the old table
to the new; DROP the old table; use ALTER TABLE to rename the new one.
