Peter Geoghegan 93ee38eade Teach pageinspect about nbtree deduplication.
Add a new bt_metap() column to display the metapage's allequalimage
field.  Also add three new columns to contrib/pageinspect's
bt_page_items() function:

* Add a boolean column ("dead") that displays the LP_DEAD bit value for
each non-pivot tuple.

* Add a TID column ("htid") that displays a single heap TID value for
each tuple.  This is the TID that is returned by BTreeTupleGetHeapTID(),
so comparable values are shown for pivot tuples, plain non-pivot tuples,
and posting list tuples.

* Add a TID array column ("tids") that displays TIDs from each tuple's
posting list, if any.  This works just like the "tids" column from
pageinspect's gin_leafpage_items() function.

No version bump for the pageinspect extension, since there hasn't been a
stable Postgres release since the last version bump (the last bump was
part of commit 58b4cb30).
