<blockquote>
<h1>2.0.46</h1>
<p>Released: January 21, 2026</p>
<h2>typing</h2>
<ul>
<li>
<p><strong>[typing] [bug]</strong> Fixed typing issues where ORM mapped
classes and aliased entities could not
be used as keys in result row mappings or as join targets in select
statements. Patterns such as <code>row._mapping[User]</code>,
<code>row._mapping[aliased(User)]</code>,
<code>row._mapping[with_polymorphic(...)]</code>
(rejected by both mypy and Pylance), and
<code>.join(aliased(User))</code>
(rejected by Pylance) are documented and fully supported at runtime but
were previously rejected by type checkers. The type definitions for
<code>_KeyType</code> and <code>_FromClauseArgument</code> have been
updated to
accept these ORM entity types.</p>

<h2>postgresql</h2>
<ul>
<li>
<p><strong>[postgresql] [bug]</strong> Fixed issue where PostgreSQL
JSONB operators
<code>_postgresql.JSONB.Comparator.path_match()</code> and
<code>_postgresql.JSONB.Comparator.path_exists()</code> were applying
incorrect
<code>VARCHAR</code> casts to the right-hand side operand when used with
newer
PostgreSQL drivers such as psycopg. The operators now indicate the
right-hand type as <code>JSONPATH</code>, which currently results in no
casting
taking place, but is also compatible with explicit casts if the
implementation were require it at a later point.</p>
<p>References: <a
href="https://www.sqlalchemy.org/trac/ticket/13059">#13059</a></p>
</li>
<li>
<p><strong>[postgresql] [bug]</strong> Fixed regression in PostgreSQL
dialect where JSONB subscription syntax
would generate incorrect SQL for <code>cast()</code> expressions
returning JSONB,
causing syntax errors. The dialect now properly wraps cast expressions
in
parentheses when using the <code>[]</code> subscription syntax,
generating
<code>(CAST(...))[index]</code> instead of <code>CAST(...)[index]</code>
to comply with
PostgreSQL syntax requirements. This extends the fix from <a
href="https://www.sqlalchemy.org/trac/ticket/12778">#12778</a>
which addressed the same issue for function calls.</p>
<p>References: <a
href="https://www.sqlalchemy.org/trac/ticket/13067">#13067</a></p>
</li>
<li>
<p><strong>[postgresql] [bug]</strong> Improved the foreign key
reflection regular expression pattern used by the
PostgreSQL dialect to be more permissive in matching identifier
characters,
allowing it to correctly handle unicode characters in table and column
names. This change improves compatibility with PostgreSQL variants such
as
CockroachDB that may use different quoting patterns in combination with
unicode characters in their identifiers.  Pull request courtesy Gord
Thompson.</p>
