Damn. Was going to collect this info as I was doing a fresh upload but it fell through the cracks of my mind. It'll probably take at least half a day to collect (a simple count(*) on the table takes 1.5-1.75 hours parallelised across 11 processes) so I'll probably have this in around 24 hours if all goes well. (and I don't stuff up the SQL :) ) AP. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
