In response to sub select as a data column  (Phong & Ronni Bounmixay <bounmixay@gmail.com>)
List pgsql-general
you were close, try the following (untesting).  You need the alias on the outer my_table for this to work


select year report_year,
          sum(amount),
          sum(select amount from my_table where year <= a.year)
from my_table a
group by report_year;
