Anyway, regarding your message: that's a very good news! :-)
I've tested, and it seems to work even for MySQL - it's clear that
some weeks ago I've done something wrong, trying to add the indexes.
After all, maybe that SQLObject can be used for this task. :-)
It would be really cool (but this is not a show-stopper issue) if
the 'id' column can be removed/not created, when it's not needed.
The executemany issue, I fear, can't be solved neither with SQLObject
or SQLAlchemy; with both - if we care about performances - we have to
extract a cursors and run its executemany method (handling manually
the different parameters styles)

I've managed to create a new index at runtime using SQLObject 0.7
class TableX(SQLObject):
col1 = UnicodeCol()
col2 = UnicodeCol()
TableX.sqlmeta.addIndex(DatabaseIndex('col1', 'col2', name="testIndex"))
TableX.createIndexes()
Tested with postgresql.
So it seems we can go on with SQLObject. The only trouble left is the
executemany hack.
