pg 7.4.2 on RH 7.3
Hi,
Am getting "Out of memory error" and pgSql is getting killed when running the
following statement in psql:
insert into tableA
select * from tableB
where testdate >= '2000-01-01' and testdate <= '2002-12-31'
TableB contains about 120 million records. The insert/select affects about
30-40M.
What's happening is that pgSql gradually takes all (well, almost) physical and
swap memory and then, I think, is getting killed by the kernel.
Qs:
1) Is this normal?
2) Is there anything I can do besides adding more memory to the box?
Thanks
