If I'm not mistaken, Postgres does not allow subselects to be used in this
context. In any case the age function should not be in quotes...
Instead, the syntax Postgres uses from the days of old would be something like
UPDATE tasktime
SET elapsed_time = age( tt.inserted_time, inserted_time )
FROM tasktime tt
WHERE row=$old_row AND tt.row = $row;
This has nothing to do with timespan.
