parse error ???

   I have one question...

  Why postgres returns parse error when i send

  select birth_time::date from table;


  parse error at or near ":"


  I use CBuilder4 and postODBC driver...


  when I write

  select date(birth_time) from table;

  it works...


  but in DataBaseExplorer the first query works fine....


  please help....
