Hallo,
first of all, thank you for fixing the ´hash table overflow problem´, I´ve tested it on a join between a 2GB and a 3MB table, it works!
Now, I tried to use the numeric type, and hit the following problem:
create table a (val numeric(10,2));
CREATE
insert into a values('123.45');
INSERT 2402633 1
create table b (val numeric(10,2));
CREATE
insert into b select sum(val) into b;
ERROR: transformExpr: does not know how to transform node 107
insert into b select float8(sum(val)) into b;
INSERT 2402643 1
One other (SQL-) question: How can I cast results to numeric directly? Using float8 cast and the following implicit cast is not very nice.
Kind regards,
