A couple of months back there was a post from someone who made a presentation about a lot of things that are 'bad' in postgres (mostly performance-wise) and a github repo that tried to fix that (in first instance with patches and the idea was to later have it either upstreamed or as an addon).

I can't find anything of this effort anymore. Does someone know what I'm talking about and what the current status of that is?

EDIT: found it: https://github.com/orioledb/orioledb

I'd love to hear what PG devs here think of his criticism and proposed solutions.
