As I wrote earlier, we (my wife and me) went to Maldives. This is brief summary, with some photos below.
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.
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.
