Steps to reproduce the issue :
1) Connect to PostgreSQL server.
2) Create a Table with oid datatype in any schema.

     CREATE TABLE "public"."oid_datatype"  (
          "col_oid"    oid NULL
     )
    GO

3) Insert some data in it.
   
    INSERT INTO "public"."oid_datatype"("col_oid")
           VALUES(1000)
    GO
 

4) Export data of this table into one file (e.g oid.txt).

5) Now try to import data from file into 'oid_datatype' table.

I receive the following error when attempting to use the data import tool to import a column of type oid using batch mode.

Import started ...

Execute batch failed: Batch entry 0 INSERT INTO "public"."oid_datatype"("col_oid")  VALUES('1000.0') was aborted.  Call getNextException to see the cause.

ERROR: column "col_oid" is of type oid but expression is of type double precision
  Hint: You will need to rewrite or cast the expression.
