-    :include_notes_from: unreleased

+    .. change::
+        :tags: bug, operations
+        :tickets: 1232
+
+        Reverted the behavior of :meth:`.Operations.add_column` that would
+        automatically render the "PRIMARY KEY" keyword inline when a
+        :class:`.Column` with ``primary_key=True`` is added. The automatic
+        behavior, added in version 1.18.2, is now opt-in via the new
+        :paramref:`.Operations.add_column.inline_primary_key` parameter. This
+        change restores the ability to render a PostgreSQL SERIAL column, which is
+        required to be ``primary_key=True``, while not impacting the ability to
+        render a separate primary key constraint. This also provides consistency
+        with the :paramref:`.Operations.add_column.inline_references` parameter and
+        gives users explicit control over SQL generation.
+
+        To render PRIMARY KEY inline, use the
+        :paramref:`.Operations.add_column.inline_primary_key` parameter set to
+        ``True``::
+
+            op.add_column(
+                "my_table",
+                Column("id", Integer, primary_key=True),
+                inline_primary_key=True
+            )
