Hi,

I've found it in 5 secounds and never tried, but this plugins should
do the trick.

http://www.symfony-project.org/plugins/sfPropelSqlDiffPlugin/0_1_6

IN THEORY:
Just create a new schema with column removed and then use plugin to
create a sql diff database.
The diff should create an alter statement.

Regards,
Maciej Aleksandrowicz
