Attached is the revised version of file_fdw patch. This patch is
based on Itagaki-san's copy_export-20101220.diff patch.
Changes from previous version are:
* file_fdw uses CopyErrorCallback() as error context callback routine
in fileIterate() to report error context. "CONTEXT" line in the
example below is added by the callback.
postgres=# select * From csv_tellers_bad;
ERROR: missing data for column "bid"
CONTEXT: COPY csv_tellers_bad, line 10: "10"
postgres=#
* Only superusers can change table-level file_fdw options. Normal
user can't change the options even if the user was the owner of the
table. This is for security reason.
