Tom explained my problem here: http://www.postgresql.org/message-id/flat/87tx0dc80x....@news-spur.riddles.org.uk I guess I'll have to live without it for now; the speed increase in queries is nice, but not humanly noticeable as the tables are not huge.

I was trying to avoid that, hence the calculated index, but it appears not to be much better. -- Bien à vous, Vincent Veyron https://legalcase.libremen.com/ Legal case, contract and insurance claim management software -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
