wxWidgets and arrays

Hello

I'm using PostgreSQL with wxDb classes from wxWidgets. But I don't know
how to define the columns in the method wxDbTable::SetColDefs. In
PostgreSQL I define the table in the next form:

CREATE TABLE sal_emp (
name text,
schedule text[]
);

.. so any idea how to define the variable schedule in wxWidgets???

Thank you in advance,
Gustavo
