5cabcfccce Modify array operations to include array's element type OID in the
array header, and to compute sizing and alignment of array elements
the same way normal tuple access operations do --- viz, using the
tupmacs.h macros att_addlength and att_align.  This makes the world
safe for arrays of cstrings or intervals, and should make it much
easier to write array-type-polymorphic functions; as examples see
the cleanups of array_out and contrib/array_iterator.  By Joe Conway
and Tom Lane.

38bb77a5d1 ALTER TABLE DROP COLUMN works. Patch by Christopher Kings-Lynne,
code review by Tom Lane.  Remaining issues: functions that take or
return tuple types are likely to break if one drops (or adds!)
a column in the table defining the type.  Need to think about what
to do here.

Along the way: some code review for recent COPY changes; mark system
columns attnotnull = true where appropriate, per discussion a month ago.

44fbe20d62 Restructure indexscan API (index_beginscan, index_getnext) per
yesterday's proposal to pghackers.  Also remove unnecessary parameters
to heap_beginscan, heap_rescan.  I modified pg_proc.h to reflect the
new numbers of parameters for the AM interface routines, but did not
force an initdb because nothing actually looks at those fields.

3bf6b8f06a Attached is an update to contrib/dblink. Please apply if there are no
objections.

Major changes:
   - removed cursor wrap around input sql to allow for remote
     execution of INSERT/UPDATE/DELETE
   - dblink now returns a resource id instead of a real pointer
   - added several utility functions

I'm still hoping to add explicit cursor open/fetch/close support before
7.3 is released, but I need a bit more time on that.

On a somewhat unrelated topic, I never got any feedback on the
unknownin/out patch and the mb_substring patch. Is there anything else I
need to do to get those applied?
