What values in your tables are unique? Are there many keyID's for the
same key or the reverse? And the same question for the keys_sigs table.
Can you give an example of your data? I would guess that the two inner
selects should not return multiple rows. Maybe I'm not getting the
picture.

Travis, I had tried nesting the selects like that, but postgres apparently
complains when subselects return multiple values.

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
