Well, as I said, the content of the text that I referred to (i.e., the text that bliako quoted) is still true but that text as quoted is in newer versions removed, rephrased, whatever you want to call it.

I was just trying to get people to be aware that search engines throw up old postgresql documentation.

It would be nice if here on perlmonks the URLs into the postgresql docs used the '/current/' unless old behaviour is specifically meant or targeted.
