0001-pageinspect-Hash-index-support_v1.patch (text/x-patch)

Hi,

Attached is a patch that adds support for hash indexes in pageinspect.

The functionality (hash_metap, hash_page_stats and hash_page_items) 
follows the B-tree functions.

This patch will need an update once Amit's and Mithun's work on 
Concurrent Hash Indexes is committed to account for the new meta-page 
constants.

I'll create a CommitFest entry for this submission.

Feedback is most welcome.

Best regards,
  Jesper
