“Help me” summary / Vacation

This post is scheduled to appear on the web when we will be on our way.

I would like to express big gratitude to all of you who helped me with my plan. As far as I know right now (Monday, 10th of October) Ula still doesn't know about the surprise trip. Which should make for a nice effect on Wednesday on the airport.

Anyway – for those of you curious on where we're going: Maldives, Kuredu Resort/Island. When we'll be back I will probably have some pictures, but not sure about it as neither I nor Ula are big fans on making photos.

I hope it will will work out fine, the place seems nice, even though the weather forecast is not in favor of us. We'll see.

During this time I do not plan to check email, write blogposts (even in case of something big would get committed to PostgreSQL), so if you'd need to contact me for something – well, after 21st I should be back online.

Thanks again for all the help.

Waiting for 9.2 – Index only scans

On 8th of October, Tom Lane committed patch:

Support index-only scans using the visibility map to avoid heap fetches.
When a btree index contains all columns required by the query, and the
visibility map shows that all tuples on a target heap page are
visible-to-all, we don't need to fetch that heap page.  This patch depends
on the previous patches that made the visibility map reliable.
There's a fair amount left to do here, notably trying to figure out a less
chintzy way of estimating the cost of an index-only scan, but the core
functionality seems ready to commit.
Robert Haas and Ibrar Ahmed, with some previous work by Heikki Linnakangas.
