Seems one keyword shy of a load; I'd prefer
ALTER TABLE blah ALTER COLUMN col SET TYPE int4;
Otherwise, every keyword that might appear after SET will have to be
fully reserved (else it couldn't be distinguished from a type name).
I like the "SET NULL"/"SET NOT NULL" variant better than SET/DROP, even
though "SET NULL" is perhaps open to misinterpretation. "DROP NOT NULL"
seems just as confusing for anyone who's not read the documentation :-(
