I can't find it in the documentation and was having no luck with WAGs.

Is there a functionality like Oracle's ROWNUM in PostgreSQL?  I need to
populate a primary key in an existing table and this has always been the
easiest method for me.

      update my_table
         set tbl_key = ROWNUM;

   If there isn't how about a method to convert an OID into float8
format?  Heck I'm open to other methods also.

TIA,
Rod
