I am developing a library to do Active Record style validations on SA
declarative instances:

I know there are differences of opinion on the value of doing
validation like this, but I am really hoping to avoid that

Ok, so I thought I might sacrifice getting all errors at once fore being
able to validate default values, by using the mapper extension's
before_update() and before_insert(). However, that also does not seem
to work as the Column's default values are not applied at that point either.

Mike,
Thank you for your quick reply.
If I understand correctly, after_flush() will get called after the SQL
is actually sent to the db server. If that is the case, then it is
too late for this validation as I would want the ability to
use a text() construct as the argument to your from_statement() call, and
specify a typemap of {'birthday':NormalDate} along with it.
