build(deps): bump sqlalchemy from 2.0.37 to 2.0.38

[dependabot]

Bumps sqlalchemy from 2.0.37 to 2.0.38.

Release notes

Sourced from sqlalchemy's releases.

2.0.38

Released: February 6, 2025

engine

• [engine] [bug] Fixed event-related issue where invoking Engine.execution_options() on a Engine multiple times while making use of event-registering parameters such as isolation_level would lead to internal errors involving event registration.

  References: #12289

sql

• [sql] [bug] Reorganized the internals by which the .c collection on a FromClause gets generated so that it is resilient against the collection being accessed in concurrent fashion. An example is creating a Alias or Subquery and accessing it as a module level variable. This impacts the Oracle dialect which uses such module-level global alias objects but is of general use as well.

  References: #12302

• [sql] [bug] Fixed SQL composition bug which impacted caching where using a None value inside of an in_() expression would bypass the usual "expanded bind parameter" logic used by the IN construct, which allows proper caching to take place.

  References: #12314

postgresql

• [postgresql] [usecase] [asyncio] Added an additional asyncio.shield() call within the connection terminate process of the asyncpg driver, to mitigate an issue where terminate would be prevented from completing under the anyio concurrency library.

  References: #12077

• [postgresql] [bug] Adjusted the asyncpg connection wrapper so that the connection.transaction() call sent to asyncpg sends None for isolation_level if not otherwise set in the SQLAlchemy dialect/wrapper, thereby allowing asyncpg to make use of the server level setting for isolation_level in the absense of a client-level setting. Previously, this behavior of asyncpg was blocked by a hardcoded read_committed.
