Bumps sqlalchemy from 1.4.46 to 2.0.3.

Release notes

Sourced from sqlalchemy's releases.

2.0.3

Released: February 9, 2023

sql

• [sql] [bug] [regression] Fixed critical regression in SQL expression formulation in the 2.0 series due to #7744 which improved support for SQL expressions that contained many elements against the same operator repeatedly; parenthesis grouping would be lost with expression elements beyond the first two elements.

typing

• [typing] [bug] Remove typing.Self workaround, now using PEP 673 for most methods that return Self. Pull request courtesy Yurii Karabas.

Released: February 6, 2023

orm

• [orm] [usecase] Added new event hook _orm.MapperEvents.after_mapper_constructed(), which supplies an event hook to take place right as the _orm.Mapper object has been fully constructed, but before the _orm.registry.configure() call has been called. This allows code that can create additional mappings and table structures based on the initial configuration of a _orm.Mapper, which also integrates within Declarative configuration. Previously, when using Declarative, where the _orm.Mapper object is created within the class creation process, there was no documented means of running code at this point. The change is to immediately benefit custom mapping schemes such as that of the examples_versioned_history example, which generate additional mappers and tables in response to the creation of mapped classes.

  References: #9220

• [orm] [usecase] The infrequently used _orm.Mapper.iterate_properties attribute and _orm.Mapper.get_property() method, which are primarily used internally, no longer implicitly invoke the _orm.registry.configure() process. Public access to these methods is extremely rare and the only benefit to having _orm.registry.configure() would have been allowing
