I got:
"Total runtime: 9.313 ms" in pgAdmin
"Total runtime: 9.363 ms" in psql.
But timing after the query finished was 912.842 ms in psql.
Cheers,
Peter Slapansky

You're right, it does... but it's quite odd, because I re-ran the explain-analyze statement and got the same results.
Still, the query now runs for about a second as mentioned before, so it's almost like something's missing from the explain, but I'm certain I copied it all.
I did this via pgadmin, but that shouldn't matter, should it?
Thank you,
Peter Slapansky

At very end of explain analyze output there should be a line:
Total runtime: ....
What do you get there?
