Finally there is a new version of patch (in attachments).

It provides multicolumn index-only scan for GiST indexes.

- little code cleanup

- example of performance test in attachmens

- function OIDs have debugging values (1111*) just to avoid merge conflicts while testing patch

Waiting for feedback.

Best regards,
