The PostgreSQL team has moved their development docs to a new site, as is documented in this thread on pgsql-www and on the PostgreSQL website. Old links were broken for a couple of days but have (mostly) been fixed by now and get redirected. However, the PostgreSQL team encourages to update links, as you can read in the thread above.
I checked for old links to the PostgreSQL developer docs with a search on SO:
I also wrote a query on data.SE to check posts and comments. I did not find a way to search for comments in the search interface on SO. The search uses considerable resources, so I picked one example and commented out the rest - including an
UPDATE statement to fix all occurrences.
Found 83 posts (currently) and 19 comments (snapshot on data.SE) for SO.
Found 7 posts and 1 comment on serverfault.SE.
Found 2 posts on superuser.SE. Fixed those right away.
I could go and edit all the posts, but I cannot fix comments. Also, this is stupid work that should be taken care of by the SQL commands I prepared, and more reliably, too. Can an admin apply the prepared UPDATE statement - provided we can agree upon its usefulness?
Should we update links to point to the new location of the development docs or to the the docs for the current release. I propose to fix the links properly as practically all of them should point to /current rather than /devel in the first place.
