[HACKERS] Index-only scans with btree_gist

Thu, 26 Mar 2015 14:33:13 -0700

I've pushed Anastasia's patch to support index-only scans with GiST, and it's time to add opclasses support for all the opclasses that are not lossy. I think at least all the btree_gist opclasses need to be supported, it would be pretty surprising if they didn't support index-only scans, while some more complex opclasses did.
Attached is a WIP patch for that. It covers all the varlen types that btree_gist supports, and int2, int4 and oid. The rest of the fixed-width types should be just a matter of copy-pasting. I'll continue adding those, but wanted to let people know I'm working on this.

Subject: [PATCH 1/1] Add index-only scan support to btree_gist.

WIP: not all datatypes are covered yet.
