Обсуждение: gist README

Hello

I see that the gist README file (src/backend/access/gist/README) hasn't 
seen any major content updates, since its initial creation, apart from 
gist insertion recovery issues [1].

I would like to ask if there are any major differences between the 
README file and postrges' code, and if the README file has the essence 
of what is happening in the gist code?

For example in commit (1f7ef548ec2e594fa8766781c490fb5b998ea46b) [2], 
another algorithm for splitting was implemented, but the paper isn't 
mentioned in the README file. The reason I am asking is that I am 
interested in gists (for a university project) and I would like to see 
how they were implemented in postgres.

Regards
Vangelis Katsikaros

We usually try to keep our README files up to date, but the GIST code
is more poorly commented than most of our code base, so it's certainly
possible that some updates are needed.
