Generate fully variant JSON schema type for columns of type JSON/JSONB

[edgarrmondragon]

Consider a JSONB column with the following values:

id (int) data (jsonb)
-------- ------------
1        {"nested": "data"}
2        ["an", "array"]
3        3.14

Then the currently generated object type will not cover all the possible values and potentially lead to schema validation errors downstream.

tap-postgres/tap_postgres/client.py

Line 85 in bcc0db1

return th.ObjectType().type_dict

Should perhaps be updated to return an empty dict.
