New issue 3786: Postgres Table Declaration Error
https://bitbucket.org/zzzeek/sqlalchemy/issues/3786/postgres-table-declaration-error

Philip Martin:

I don't think I had this issue previously, but I have noticed since using:

python: 3.5.2
sqlalchemy: 1.0.13

I run into the error doing the following:

```python
table = sa.Table('foobar', sa.MetaData(), sa.Column('foo', sa.CHAR(7), primary_key=True)
engine.execute(table)

Traceback (most recent call last):
    engine.execute(table)
  File "/anaconda/lib/python3.5/site-packages/sqlalchemy/engine/base.py", line 1991, in execute
    return connection.execute(statement, *multiparams, **params)
  File "/anaconda/lib/python3.5/site-packages/sqlalchemy/engine/base.py", line 914, in execute
    return meth(self, multiparams, params)
  File "/anaconda/lib/python3.5/site-packages/sqlalchemy/sql/schema.py", line 65, in _execute_on_connection
    return connection._execute_default(self, multiparams, params)
  File "/anaconda/lib/python3.5/site-packages/sqlalchemy/engine/base.py", line 942, in _execute_default
    ret = ctx._exec_default(default, None)
  File "/anaconda/lib/python3.5/site-packages/sqlalchemy/engine/default.py", line 952, in _exec_default
    if default.is_sequence:
AttributeError: 'Table' object has no attribute 'is_sequence'
In[80]: table.create(engine)
```

The ddl statement does execute when I run:

```python
engine.create(table)
```
