I've rebased WIP patches for file_fdw onto Itagaki-san's recent
copy_export patch.

Interface of NextCopyFrom() is fixed to return HeapTuple, to support
tableoid without any change to TupleTableSlot.

Please apply patches in this order:

1) patches for FDW API (NOT attached to this message)
These patches are attached and described in this message.

2) copy_export-20110114.patch (NOT attached to this message)
This patch is attached and described in this message.
http://archives.postgresql.org/pgsql-hackers/2011-01/msg01066.php

3) 20110114-copy_export_HeapTupe.patch
This patch fixes interface of NextCopyFrom() to return results as
HeapTuple.

4) 20110114-foreign_scan.patch
This patch adds HANDLER option of FOREIGN DATA WRAPPER, and
ForeignScan executor node. Note that no wrapper is available in this
patch.

5) 20110114-file_fdw.patch
This patch adds contrib/file_fdw, foreign-data wrapper for server-side
files. Supported file formats are similar to COPY command, and
COPY options except "force_not_null" are accepted as generic options
of foreign table.
