You just posted this today? This isn't the first time your article has been on the front page of HN. I actually still have your article "saved" in a tab in chrome from the last time it was on HN. It made quite an impression on me, I'm in the process of moving our dev environments from sqlite to postgres, so that we can start adding some of this functionality. Thanks.

To be honest, I'm quite surprise to see that somebody posted this article again.. I don't know HN rules when you can post again something.

I'm not going to complain about it :)

I think you can repost about a year. It could have changed tough.

I don't know when it was posted, but it definitely was less than one year ago. My main data point is that it still is living in an open tab in Chrome. I have a couple of sites which allow submitting links. I know people can get around my requirement that they are unique pretty easily. I'm sure HN is more sophisticated but I think that just having different url parameters might qualify as a different link? Sometimes a url parameter change really does point to a different page, so it might not be possible to eliminate duplicates that have the same url with just different params.

URL parameters don't qualify as a different link (or else anyone submitting a url without removing them would have unique posts). I always thought the rule had to do with comments being allowed on the post, which, I believe, are based on comment activity. My assumption was as long as an article still allows comments, resubmissions don't become new posts.

I don't know why and I can't help you, in both case I didn't post it. But we don't have multiple url for our blog. I find it odd to be honest as the post was posted on HN the 29th of September (base on Google Analytic)

It's definitely a cool article, I don't mind seeing it twice. I love the idea of having these tools with postgres and not having to use thinking sphinx or solr right as quickly.
