This error is usually produced because a column of that name does not exist.

Since you are using a mixed-case column-name, I'm guessing that's the
cause of the problem. If you create a column mixed-case by quoting it:

CREATE TABLE employee (
   "employeeID" int4
   ...
)

Then you need to quote it when you use it:

SELECT "employeeID" FROM employee;

If you don't quote when you create, then the column is case-insensitive.

See the mailing-list archives for plenty of details.
