Dear all,

I am using
copy tableA from '/tmp/A.data' and have the following error:

Unable to identify an operatior '=' for types 'varchar'
You will have to retype this query using an explicit cast.

What is "an explicit cast"?

Something like this:
SELECT '0.80'::float;
The '::float' tell Postgresql to cast '0.80' (a string) in to a real number
(float).

But you can't use an explicit cast in your query. I think the problem comes out
of your table definition.

Best regards,
Boris
