It surprised me when I saw Oracle's behavior. Informix supports DDL
within transactions quite happily:
create table foo22 (id int,myvalue varchar);
create table foo23 (id int);
begin;
alter table foo22 drop (myvalue);
alter table foo23 add (mynewvalue varchar);
rollback;
INFO - foo22: Columns Indexes Privileges References Status ...
Display column names and data types for a table.

Column name Type Nulls
id integer yes
myvalue varchar(1,1) yes
AND
INFO - foo23: Columns Indexes Privileges References Status ...
Display column names and data types for a table.

QED.
It's a strong point in PostgreSQL's favor that it behaves in what I
regard as a sane manner. That Oracle stuff makes me shudder -- it's unclean.
