Maybe postmaster running with -F on one system but not the other?
Or referential integrity checks defined on one table and
not the other?
Try to run a vacuum on the box with slow inserts (don't know if that
helps, though).
Run a /sbin/hdparm -t harddisk, to compare the speed of the harddisks.

Hi.
here's my scenario: table employee has emp_id and employee

The following works fine: (get all employees who have sold
something)
SELECT emp_id FROM employee WHERE emp_id IN (SELECT emp_id FROM

As someone else pointed out you can upgrade to 7.1. Or you can add your

I've included the C source and SQL create script. You'll need to do this
as the postgres superuser. And you'll probably need to edit the SQL
script and adjust the path of the .so file. The .c

To start with, I think your queries will be faster if you don't use IN,
but instead used regular joins or EXISTS whenever possible

Are there any NULL values in workorder.emp_id? If so, you need to exclude
them (... FROM workorder WHERE emp_id

Probably you have some NULL values in workorder. See past discussions
about why NOT IN and NULL

Sequences don't have indexes, so they don't need reindexing.

Thanks for the insight. The problem is that logging ax is basically a
convenience for the end user. (A is a user table) I must reference B
from C. If I also add an A reference to C, I want the A reference to

It's a double-edged sword. Invoking it is as simple as adding a line to a

Reindex a sequence? Not sure what you mean by that. You can set the value to

If you mean compact the values used so there
