trying to learn usage

[ionapjolive]

I am trying to incorporate this into a project. I set up my materialized view as in this example and included the corresponding code needed in my db index.js file, but I am getting this error when trying to test the search function:
SequelizeDatabaseError: function ts_rank(text, tsquery) does not exist
I do not know if this has something to do with not using the migration, although I am not seeing how that is used in this example.

Perhaps it is because my versions of Postgres and Sequelize are newer.

Thanks.
