- don't hardwire "subqueries" requirement in the base, mysql < 4.1 isn't working anyway
- don't need explicit FB/PG exclusions in test_returning
- hit db.connect() for the returning requirement
become an externally usable package but still remains within the main sqlalchemy parent package.
in this system, we use kind of an ugly hack to get the noseplugin imported outside of the
"sqlalchemy" package, while still making it available within sqlalchemy for usage by
third party libraries.
can now provide "bind expressions" and
"column expressions" which allow compile-time
injection of SQL expressions into statements
on a per-column or per-bind level. This is
to suit the use case of a type which needs
to augment bind- and result- behavior at the
SQL level, as opposed to in the Python level.
Allows for schemes like transparent encryption/
decryption, usage of Postgis functions, etc.
[ticket:1534]
- update postgis example fully.
- still need to repair the result map propagation
here to be transparent for cases like "labeled column".
