Custom a generated dbt transformation

[tomt00001]

I have an Airbyte job in which I want to customize the field types on the destination database (postgres). I have extracted the generated dbt transforms and have it working in a dbt project with just one of the models in it.

I am new to using dbt but I am looking to customize a particular field instead of being generated as text to be jsonb in the postgres destination. It was jsonb in the source and got converted to text along the way. My data warehouse has a lot of views that depend on that, the long term plan is migrate away from that but in the short term I need to get those columns into jsonb format.

Any suggestions?
