Dialect specific migration with Alembic

DDL

Certain SQL dialect specific SQL including triggers and stored procedures are not abstracted away by SqlAlchemy. In those cases SqlAlchemy provides a DDL interface that can be connected to events that conditionally trigger the appropriate dialect specific code.

ddl = sqlalchemy.DDL(custom_pg_trigger)

"""Creating thread safe and managed sessions using SQLAlchemy.

The sessions that are created are expected to be:
- thread safe
- handle committing
- handle rolling back on errors
- handle session removal/releasing once context or thread is closed.
