Hi all,
I have installed postgresql(8.1.4) data dir on a partition (/data) which rests
on a separate disk from OS disk. The install dir is default (usr/local/pgsql).
Now when i use use pgbench with scaling factor of 1000 it creates a whooping 15

maybe /data is a symlink?

I bet you're running a default installation of postgres which has it's
data in /var.
Check your real data directory by running 'ps auxww|grep post', and see
what's after the '-D' parameter... and then when you figure out that the

Maybe you switched full statement logging on in postgresql.conf? This can

Unless you're using tablespaces, the server will definitely not write

Note that whether you have CASCADE or not is not the issue --- if you
are doing a delete in a foreign-key-referenced relation at all, you
are going to have a trigger event per deleted row no matter what the

Recent experience suggests this is the case but my reading of the docs

fundamental type of the column, nor are we a

'epoch' returns the number epoch seconds that comprise the interval.
That differs from 'seconds' which just returns the "seconds place",

Yes. Doing otherwise would require an unreasonable amount of
