Hi all,
I've prepared a release timeline for the PostgreSQL Wikipedia
article[1,2], from 1995 to present. It was prepared using MediaWiki's
EasyTimeline Perl utility[3]. I think the docs say it can output SVG
too, but I've only used the MediaWiki built-in. Regardless, it's free
for anyone to use and/or modify.
