postgreSQL 8beta

Hi,
does postgresql have a datatype 'other' which in hsqldb is an Object? I
am trying to convert the table below into postgreSQL 8:


  create table TIMERS (
  TIMERID varchar(50) not null,
  TARGETID varchar(50) not null,
  INITIALDATE timestamp not null,
  INTERVAL bigint,
  INSTANCEPK other,
  INFO other,
  constraint timers_pk primary key (TIMERID)


regards


Andrew
