Casting errors when using Redshift as a data source

No

I've been trying to migrate from Redshift to Postgres with a simple command

load database
    from uri
    into uri
including only table names matching 'table' in schema 'schema'
with
    data only
;

(The table is already created)

But I get the following error message:

Database error 42846: cannot cast type boolean to character varying

followed by a query. I won't show the query, but it is something like this

SELECT boolean_column::text ...

which causes the error
