Hi, hackers!
There are first results of my work on GSoC project "Index-only scans for GIST".
1. Version of my project code is in forked repository
https://github.com/lubennikovaav/postgres/tree/indexonlygist2
Patch is in attachments
- This version is only for one-column indexes
- fetch() method is realized only for box opclass (because it's trivial)
2.
I test Index-only scans with SQL script box_test.sql
and it works really faster. (results in
box_test_out)
I'll be glad to get your feedback about this feature.

Best regards,
Lubennikova Anastasia
