Postgresql - converting text to ts_vector

问题

Sorry for the basic question.

I have a table with the following columns.

      Column |  Type   | Modifiers 
     --------+---------+-----------
      id     | integer | 
      doc_id | bigint  | 
      text   | text    | 

• I am trying to do text matching on the 'text' (3rd column)
• I receive an error message when I try to text match on the text column. Saying that the string is too long for ts_vector.

I only want observations which contain the words "other events"

    SELECT * FROM eightks\d
    WHERE to_tsvector(text) @@ to_tsquery('other_events')

I know that there are limitation to the length of the ts_vector.

Error Message

   ERROR:  string is too long for tsvector (2368732 bytes, max 1048575 bytes)

How do I convert the text column into a ts_vector and will this resolve my size limit problem?Alternatively, How do I exclude observations over the maximum size?

Postgres version 9.3.5.0

Here is the reference to the limit limit

Thanks
