Attached is v34, which has this change. My plan is to commit something
very close to this on Wednesday morning (barring any objections).
Other changes:
* Now, equalimage functions take a pg_type OID argument, allowing us
to reuse the same generic pg_proc-wise function across many of the
operator classes from the core distribution.
* Rewrote the docs for equalimage functions in the 0001-* patch.
* Lots of copy-editing of the "Implementation" section of the B-Tree
doc chapter, most of which is about deduplication specifically.
