title: tsvector in sqlalchemy
body: <p>I've been looking for a way to use tsvector in sqlalchemy (simply like other ones such as INTEGER, etc), but so far it's not clear to me how to do this. I've read that tsvector can be implemented as a type using <a href="http://docs.sqlalchemy.org/en/rel_0_8/core/types.html#sqlalchemy.types.UserDefinedType" rel="noreferrer">UserDefinedType</a>. After some attempts I'm getting nowhere, someone has a simple way to do this? thanks</p>
