according to [this code](https://github.com/zzzeek/sqlalchemy/blob/master/lib/sqlalchemy/dialects/postgresql/base.py#L1303),

there is only
'interval': INTERVAL,
'interval year to month': INTERVAL,
'interval day to second': INTERVAL,
and no [others](https://www.postgresql.org/docs/9.6/static/datatype-datetime.html)
YEAR
