Index postgresql_include renders the columns incorrectly

[CaselIT]

Describe the bug
Trying to add an index like

    sa.Index(
        "my_index",
        my_table.c.a_column,
        postgresql_include=[my_table.c.b_column],
    )

generates a migration that's not valid python, both on the upgrade and downgrade. Downgrade renders:

# upgrade
op.create_index('my_index', 'my_table', ['a_column'], unique=False, postgresql_include=[Column('b_column', Text(), table=<my_table>)])
# downgrage
op.drop_index('my_index', table_name='my_table', postgresql_include=[Column('b_column', Text(), table=<my_table>)])

Expected behavior
The postgresql_include renders correctly

To Reproduce
Please try to provide a Minimal, Complete, and Verifiable example, with the migration script and/or the SQLAlchemy tables or models involved.

import sqlalchemy as sa

my_table = sa.Table('my_table', sa.MetaData(), Column('a_column', Text()), Column('b_column', Text()))
sa.Index("my_index", my_table.c.a_column, postgresql_include=[my_table.c.b_column])
