Maybe you're using an old psql?  My 8.2 psql shows

regression=> \h alter table
Command:     ALTER TABLE
Description: change the definition of a table
Syntax:
ALTER TABLE [ ONLY ] name [ * ]
    action [, ... ]
...
where action is one of:
...
    ALTER [ COLUMN ] column TYPE type [ USING expression ]
...
