I suspect you're right. I've looked at the code and it will be very difficult (especially if I want to do it as an extension rather than patching Postgres) and with all the stuff I'd need to do to make it work you're also right that it probably won't improve upon just using primary key Ids.
I've scrapped any further exploration; too hard and no real benefit. -- View this message in context: http://postgresql.nabble.com/Learning-to-hack-Postgres-Keeping-track-of-ctids-tp5923649p5924248.html Sent from the PostgreSQL - hackers mailing list archive at Nabble.com. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
