[dependabot-preview[bot]]

Bumps sqlalchemy[postgresql_psycopg2binary] from 1.4.7 to 1.4.8.

Release notes

Sourced from sqlalchemy[postgresql_psycopg2binary]'s releases.

1.4.8

Released: April 15, 2021

orm

• [orm] [bug] [regression] Fixed a cache leak involving the _orm.with_expression() loader option, where the given SQL expression would not be correctly considered as part of the cache key.

  Additionally, fixed regression involving the corresponding _orm.query_expression() feature. While the bug technically exists in 1.3 as well, it was not exposed until 1.4. The "default expr" value of null() would be rendered when not needed, and additionally was also not adapted correctly when the ORM rewrites statements such as when using joined eager loading. The fix ensures "singleton" expressions like NULL and true aren't "adapted" to refer to columns in ORM statements, and additionally ensures that a _orm.query_expression() with no default expression doesn't render in the statement if a _orm.with_expression() isn't used.

• [orm] [bug] Fixed issue in the new feature of _orm.Session.refresh() introduced by #1763 where eagerly loaded relationships are also refreshed, where the lazy="raise" and lazy="raise_on_sql" loader strategies would interfere with the _orm.immediateload() loader strategy, thus breaking the feature for relationships that were loaded with _orm.selectinload(), _orm.subqueryload() as well.

  References: #6252

engine

• [engine] [bug] The _engine.Dialect.has_table() method now raises an informative exception if a non-Connection is passed to it, as this incorrect behavior seems to be common. This method is not intended for external use outside of a dialect. Please use the Inspector.has_table() method or for cross-compatibility with older SQLAlchemy versions, the _engine.Engine.has_table() method.

sql

• [sql] [feature] The tuple returned by CursorResult.inserted_primary_key is now a _result.Row object with a named tuple interface on top of the existing tuple interface.
