Please enter a FULL description of your problem:
------------------------------------------------
When you try to use the SUM aggregate on each of two
columns from different tables, the results are
incorrect.
I'm trying to select the sum of an int4 column from
one table and the sum of an int4 column from another
table but the results are incorrect for the second
sum. Sometimes the result columns look like they were
arrived at by repeatedly doubling the true sum a
varying number of times (are the bits getting
shifted?). I can't figure out the pattern.
Please describe a way to repeat the problem. Please
try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
=> create table t1 (a int);
CREATE
=> insert into t1 values (1);
INSERT 155081 1
=> insert into t1 values (1);
INSERT 155082 1
=> create table t2 (a int);
CREATE
=> insert into t2 values (1);
INSERT 155092 1
=> select sum(t1.a), sum(t2.a) from t1, t2;
sum|sum
---+---
2| 2
(1 row)
If you know how this problem might be fixed, list the
