Yea, I was pretty unclear exactly what the email was saying.

Ah, OK, exactly what should the TODO item text be? Can you modify the TODO? I don't understand the TODO text I had. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + If your life is a hard drive, Christ can be your backup. +

What I thought the TODO was about was extending the indexam API so that
the actual key values stored in the index could be retrieved (from
indexes that support this, which needn't be all of them). This would
allow non-indexable qual conditions to be checked on the index value
before visiting the heap. The canonical example is fully checking a
LIKE condition on the index key.
We've been discussing exactly this point over in the GIT-index thread...

I don't understand the TODO text I had. Got it, TODO clarified: * Allow index scans to return matching index keys, not just the matching heap locations -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + If your life is a hard drive, Christ can be your backup. +
