Thanks for the "ctid" trick. The code below worked fine
for rec in select * from fromemail_trades loop
update fromemail_trades set recordid = row where ctid = rec.ctid;
row := row -1;
end loop;
The first line is a little different from your's:
FOR row IN SELECT ctid, * FROM table FOR UPDATE LOOP
How important is it to specify ctid in the select and to add 'for update'?
it's not. also, without a where clause you are better off just locking
the table (lock table...). also, the above loop is better achieved
via a single query.
